if 1 lbs = 0.5 kg then that is correct .

so usa-official will say indonesia-country-education-minister is wrong for saying '1 pon = 5 ons' or '1 lbs = 5 hecto-gram' .
but maybe current indonesia-country-education-minister is not saying '1 pon = 5 ons' anymore , not saying '1 lbs = 5 hecto-gram' anymore .

but i think all vertical-line in
https://upload.wikimedia.org/wikipedia/commons/e/ec/World_Time_Zones_Map.svg from https://en.wikipedia.org/wiki/Time_zone
is suppose to be straight .

https://upload.wikimedia.org/wikipedia/commons/e/ec/World_Time_Zones_Map.svg show time-zone 'gmt - 12' is same like 'gmt + 12' ,
that is confusing . so maybe ??? put pago-pago-city in time-zone 'gmt - 11' but that is also confusing because high-minus-value is suppose to mean
very late , maybe pago-pago-city is suppose to use 'gmt + 11' .

i think 'gmt + 13' , 'gmt + 14' is not suppose to exist .
kiribati-country->line-islands use 'gmt + 14' .
tonga-kingdom use 'gmt + 13' .

i think 'gmt + 11' is most forward . 'gmt - 12' is most backward . 'gmt + 12' ought to be deleted because 'gmt + 12' is same like 'gmt - 12' and
that is confusing or maybe delete 'gmt - 12' and keep 'gmt + 12' .
if 'gmt - 11' become 'gmt + 11' then 'gmt' become 'gmt + 2' according to manual-counting using
https://upload.wikimedia.org/wikipedia/commons/e/ec/World_Time_Zones_Map.svg from https://en.wikipedia.org/wiki/Time_zone
.

so 'gmt + 2' become new gmt and there is lot of country in time-zone 'gmt + 2' .
i think modifying gmt-location can become politic-problem because if there is new country becoming new gmt-location then
rolex.com->gmt-master-bracelet-clock devalue and many politician is rolex.com-bracelet-clock-owner .

if most forward clock is 'gmt + 12' and most backward clock is 'gmt - 11' ( which sounds better ) then
pago-pago-city where currently use 'gmt - 11' become 'gmt + 12' , and then 'gmt' become 'gmt + 1' 
according to manual-counting using
https://upload.wikimedia.org/wikipedia/commons/e/ec/World_Time_Zones_Map.svg from https://en.wikipedia.org/wiki/Time_zone
.

and there is lot of country in time-zone 'gmt + 1' .

but my statement 'maybe usa->american-samoa-territory->pago-pago-city->ppl is 1-st ppl on earth who see full-moon'
is maybe false because timeandate.com have history/reputation showing inconsistency : find 'addition 1 jan 2024 1:46 am est' . 

and maybe 1-st location on earth who see full-moon become different 1 month later , 2 month later .

Hunter Biden

Rolex Collection
A Reader wrote in recently inquiring about what watch Joe Biden wore during most recent Presidential Debate and it turns out
Joe was wearing a Seiko Chronograph which Nick Gould identified as a watch Biden had been wearing for 10+ years.
This naturally made me curious, and I happened to notice Democrat candidate for the Presidency of the United States son,
Hunter Biden wears multiple different Rolex models. In the photo below from Popular Mechanics we see Hunter Biden rocking a Batman GMT-Master.

We see Hunter Biden again in the image wearing his Batman Rolex GMT-Master in the photo below.

In this next photo we see Hunter Biden wearing a Rolex Explorer model with the classic 3, 6, 9 dial.

In this last image we see Hunter Biden wearing a Rolex Datejust on a Jubilee Bracelet.

On time with Paris Hilton

7 min read

Paris Hilton, who has an impressive collection of purses as well as watches, launched her own collection of timepieces in 2007.
Like her, they are “made to sparkle”.
I have this image of you boarding a Barbie-pink plane with a couple of chihuahuas under your arm, a watch on each wrist to keep track of
time zones, and bare-chested flight attendants to take care of your three dozen Vuitton trunks. Caricature or close to the truth?

(laughs). Well to start with, I don’t travel in Barbie-pink planes with a couple of chihuahuas, and the cabin crew keep their shirts on!
As for the amount of luggage I take, it depends where I’m going and how long I’ll be away. If it’s for the Cannes Film Festival,
for example, I’ll probably take a dozen suitcases. I actually don’t travel with Vuitton luggage any more. Baggage handlers aren’t
careful enough, either out of pure jealousy or because they don’t realise how much it’s worth. And I only wear one watch at a time.
My favourites are a Rolex GMT-Master-2 in pink gold with diamonds and my Rolex-Daytona in Everose gold.
It means the world to me. I’ve always loved Rolex watches. They’re well-designed, reliable and always in style.
A Rolex is always a sign of good taste.

Do you remember your first luxury watch?
Yes. I was in New York and I was 15 years old. Donald-Trump had just opened his modelling agency and he wanted me to be
the first model on the books. He asked my parents’ permission and they refused. I can still hear my father saying,
“When Paris is age 18 she can do whatever she wants with her life, but no way is she becoming a model right now!”
I didn’t listen to them. A couple of weeks later I was the face of Iceberg campaign, photographed by David-LaChappelle.
I used my first fee to buy Swarovski crystals, a Dolce & Gabbana bra and a 2-nd-hand Cartier-watch (laughs).
It was a solid silver Tank with a crimson crocodile strap!

Paris Hilton Paris Hilton

When did you really develop a passion for watches ?
From the age of twenty or so. Before watches, I was into purses. I was given my first Chanel purse for Christmas when I was age 5.
It was tiny and pink. It was one of a lot of purses, including several Birkins, that were stolen in 2007, along with most of
the other valuables I owned. The thieves were a gang of teenagers who called themselves the Bling Ring. Not to mention the watches.
They took advantage of the fact I was out of town to come back several times and help themselves. Now I only have 3,000 purses and 500 pairs of shoes…

Three thousand purses? Seriously?
Yes, seriously. I have five walk-in closets on different floors of my home and they’re all colour-coded. What I mean is,
I store all my pink bikinis, shoes, clothes and accessories in one closet, white in another, beige in another, etc.
Everything else is in the garage because I’ve run out of space!

Were you able to recover your valuables after the gang was arrested?
No. I didn’t get back anything worth recovering. Anything that had monetary or sentimental value, like the watches, necklaces and rings
I inherited from my grandmother, had been pawned or sold at Venice Beach stores, even garage sales. All the stuff that came down to me
through my family has been scattered to the winds. These were all things that meant a lot to me and I hate to think I’ll never see them again.

Paris Hilton 
You have been known to wear an $18 million watch. Isn't that asking for trouble?
I like nice things, things that no-one else has, and I don’t see why I should change the way I live just because my home was burgled.
Of course, at some point you do wonder whether you should maybe keep a low profile. But I’m a woman and I like pretty, shiny things.
What really annoys me is that people think of me as a daddy’s girl. You wouldn’t believe the stories that are told about me.
Someone wrote that I’ve never done a day’s work in my life when I work full-time developing my company.
Supposedly I got my first credit card when I was age 13 , which is a complete lie. When I was age 17,
I begged my parents to let me model but they said no, not until I’d finished my studies. After that I moved to LA and
refused to accept any money from my family. I wanted to succeed by myself. I single-handedly built my empire.
My great-grandfather was a bellboy before he became a hotel magnate. He was a fighter and I get that from him.
I wanted to be known for myself, which is why I decided to create my own brand. At first I wanted to call it “Paris”,
but I knew I could achieve greater things if I added my surname. After I appeared in The Simple Life, you wouldn’t
believe the number of people who had me down as a dumb blonde. Deep down, it doesn’t bother me. I know who I am. Believe me,
you don’t build up a $300 million business without a couple of brain cells!
As well as your fragrances, hotels, cosmetics, lingerie and other "Paris Hilton" branded products, you also have your own watch collection.

That’s right. Since 2007. Like me, they’re made to sparkle! They’re original, fun to wear and affordable. The idea was that women
should be able to wear something stylish and elegant on their wrist without having to empty their bank account… or their partner’s! (laughs)

Where does your interest in watches come from?
From my grandmother. She was always very careful about how she looked and, as a little girl, I was totally in awe.
For me, my grandmother was the epitome of glamour. She had this gorgeous marquetry box, set with turquoises and filled
with treasures including some gold and platinum watches – gifts my grandfather gave her that she cherished.
True love tokens! If I have children, I’d want to give them all my love, of course, but I’d also want them to inherit
my passion for beautiful things. I’m lucky enough to have travelled extensively and to have met wonderful artists, capable of
transforming an idea into a work of art. This is one of the reasons I find watches so fascinating. A watch starts out as an idea,
then it becomes a drawing with calculations and dimensions. From there it becomes bridges, pinions, a winder and other micro-components
on a workbench which then have to be assembled within a very small space. Taken separately, none of these parts has any interest.
It’s only once they’ve been assembled by the master watchmaker, only when they’re connected to each other, that they become something.
Imagine giving life to inanimate pieces of metal. There’s something magical about a watch. It’s like a tiny heart beating on your wrist
with the sole purpose of giving the time, the date and maybe moon phases. Personally, I only look for basic functions in a watch.

Paris Hilton Paris Hilton
And if Paris Hilton were a watch...
It would be sparkly and definitely pink! It would always give the right time because punctuality is a sign of respect towards
the person waiting. I’m the complete opposite to Karl Lagerfeld who claimed he hated wearing a watch as an excuse for the fact he was so often late.
You talked about being original. You certainly have an original name.

I know. I hear there’s a city in Europe with the same name. Honestly, you French, you have no imagination! (laughs)

LPG vs. Propane
Is liquified petroleum gas the same as propane? Liquified petroleum gas — or LP gas — is a flammable hydrocarbon gas made from propane, 
butane and small amounts of other hydrocarbons like propylene and butylene. Propane and butane are flammable hydrocarbons with different 
chemical formulas. LP gas comes from refined crude oil and it’s extracted from natural gas streams as it emerges from the ground.

How long will 1 lbs LP tank last?
That answer really depends on what you’re grilling, how often, and sometimes even weather conditions. We’ve designed the Traveler to be fuel efficient. 
Internal tests lead us to believe that you’ll get over an impressive 2 hour grill time with a 1 lbs disposable LP tank.

Looking for feedback on burn time for 1 lbs propane bottles OR # of bottles used per X day trip. Be using a 2 burner Coleman , 
10,000 BTU burners for breakfast, dinner, washing, hot drinks. Did do some searching but nothing obvious on this topic.

1 lbs propane is roughly 20,000 btu so a 10,000 btu burner will only run for approximately 2 hrs on high on 1 lbs tank.

Gas consumption
Question

Hey guys, I’m in the early stages of considering opening a food truck! One thing I’m struggling to work out is how much gas we could potentially 
get through (I’m talking gas for the cooking not for the driving). Could anyone tell me what equipment you use, how long you run it for and 
how much gas you get through?

Gas as in propane or gas as in gasoline?

Propane:

 Anything with a gas burner (stove, oven,etc) is measured in BTU/hours. When you see 40,000 BTU it means 
 "This burner/oven/stove burns 40,000 BTUs of propane in ONE hour". Find out the BTU ratings of your gas appliances.

 1 lbs propane has 21,500 BTU of potential energy. 1 gallon propane provides 91,500 BTU energy. So that 40,000 BTU example can burn 
 for 2.28 hours on 1 gallon propane. Or 0.5 hour on 1 lbs propane.

 Typically food trucks have 1 or 2   100 gallon propane tanks (EDIT: It just occurred to me they are 100 lbs typically and not gallons), 
 so assuming two you have 4,300,000 BTU of potential heat energy stored on the truck when you are full. (21500 BTU per lb x 200 LBS = 4300000 BTU)

Math:

 Add up all of your BTU ratings of your gas burners/appliances. This is your burn rate. This is how many BTUs (if everything is running) 
 you will burn in 1 hour.

 Figure out how many lbs propane you will store onboard. Multiply that by 21,500. This is the number of BTUs of stored energy your propane has.

 Divide the stored BTUs into your burn rate. This is how many hours of cooking time you have.

COST: Google "national price of propane" for the weekly breakdown of the price per gallon of propane near you. It's typically more expensive 
in the winter. Here in California it is about $3/gallon in the cold months.

Gasoline/diesel for your generator/electric items.

This is tougher. You need to know your generator model, and its consumption at 1/4, 1/2, and full load (usually rated in hours on a full tank of 
gas or gallons). Once you have that, you then need to add up all of your wattage and then divide your generator's capabilities (i.e. 7000 watts) 
by your added up wattage. This will give you your operating load. From there you can see where it stands on the scale between your generator's 
runtime specifications.

COST: This is the same price per gallon of gasoline or diesel you would put in a regular car or truck (or in your food truck)

I hope this helps.

How many uses out of the coleman 1lb propane tank?
Awaiting Flair

Hello,

I am going camping tomorrow at a place that currently has burn ban in affect and can't use the grill at the camp like I usually do, 
so I bought the two burner coleman stove and a 4 pack of the 1lb propane cylinders i have never used this before so I looking for how many uses 
you get out of the tanks. I will be at the campsite from saturday afternoon thru tuesday morning and wanted to make sure this is enough 
to last through the trip.

Thanks for the help.

Depends on how long you use the stove at once and how many times per day, etc.

One of those cylinders with a pound of propane in it has about 21,500 btus of energy.

So, assuming that the burners on your stove are 10,000 btus each, on one cylinder you should be able to burn both of them wide open for an hour.

Four cylinders gives you four hours of full burn.

Back of the napkin math but it should give you a rough idea.

Also, boiling 2 cups of water typically takes anywhere from 3-6 minutes on a stove like yours, depending on a lot of things like altitude, pot size, 
starting water temperature, etc.

Hope this helps.

How long do these propane bottles last?

Let's say 5 days with a Coleman stove cooking twice a day and a Coleman lantern running 3-4 hours a night as well. 
Are these 2 bottles enough or should I grab an additional? Thanks!

There are about 22,000 BTUH in a pound of propane. Divide 22,000 by the rated input of your lantern and that will give you the approximate run time.

The Coleman Website shows the run times for their lanterns.

I vote for 2 grill system. 1 larger and 1 smaller. I do most of my cooking on a Q-200, but I have a SS Genesis Platinum C and 
a Genesis 1000 for larger cooks or cooking for several people. Having 2 grills allows more versatility as well. 
I can do steaks or whatever on 1 grill and then cook my Asparagus on my Q200 so everything comes out at the same time. 
You can cook 2 different foods on a single Genesis, but it is easier on 2 different grills with varying temps.

2 Burner or 4 burner??

I’m really interested in getting the air fryer combo exclusive to Walmart. Any reason (other than size) to get a 4 burner over the 2 ? 
Do I lose anything from a temperature control perspective?

With propane grills the additional zones are really helpful to have, not sure if the same holds true with griddle cooking though.

Thanks!

Four zones is definitely nice to have. It gives you a heck of a lot of flexibility. For example, for breakfast, you can be cooking meats 
on high on 2 zones, do pancakes or eggs on one zone on low, and hold stuff warm in the last zone with the burner off...

Stop buying those. They’re bad for the environment, have to be disposed of as hazardous waste, and a huge waste of your money. 
Get a 5 lbs propane tank and a hose adapter. From then on, you will only be paying for the propane you use.
