With just four numbers, you can given the exact time. (no AM/PM)
It's the international norm.

Because we're not sheeple and don't feel obligated to follow the rest of the lemmings.

It's not "normal". It's an option. Some people choose to use it, some don't.

The USA still uses the imperial system for measuring temperature, weight and length, why would they need a standard?

you can't really expect anything useful out of Americans, they don't even use the metric system

lol

The American military does use a 24 Hr. Clock.

We use both here.

Denisty of milk = 1.003073 - 0.000179T - 0.000368F + 0.00374N
where T = temperature; F = percentage fat; N = percentage solids (non-fat).

But I get your point, 1L milk is practically 1kg. I studied chemistry as an undergrad, so I'm very pro-metric. Hell, give me the temperature in kelvin please!

Milk is actually more dense than water (which the metric system uses as standard; 1 litre water = 1 kg water), thus the milk weighs more. This means one litre of milk does not equate to one kilogram of milk.

Don't be pedantic. You can't even estimate without the metric system.

Personally, I prefer the 12-hour system despite being one of those madcap Europeans.

I also use a mixture of Imperial and metric depending on the situation, to my occasional bafflement.

What does this mean?

I travel to two dozen countries outside the US very year and I rarely see 24 hour clocks.

You must travel to 24 different countries than I do. Aren't all other countries, by default, outside the US?

:sigh:

Most digital clocks I see throughout Western/Central/Eastern Europe are 24-hour based. Scandinavia as well. Through French-Indochina as well (when I did see a public digital clock).

However, I don't get to the South American countries, India, China or Japan that often.

Really? I lived in Germany for 4 years and traveled most of Europe and they all used the 24 hour system. I also traveled most of the middle east and it was the same there.

Americans fight change. In the 70's we tired to switch to the metric system and it was ignored by everyone. People simply resist change. I have used both and prefer the 24 hour system as well as the metric system to what we currently have. It is a lot easier.

It's really not easier in the US. Try telling someone you'll meet them at 1600. Odds are you're going to waste even more time explaining that you use the 24-hour clock because "it's easier" to explain this every time rather than say "I'll meet you at 4." Or try asking for 30 liters of gas at the gas station. If the gas attendant asks, just say "Oh it's easy... just multiply by 0.264 to get gallons."

Use whatever time or measurement system that your audience is used to.

Most of the rest of the world went through the transition over time. It's a much better system, the US will change eventually. The imperial system is ludicrous, I wish it would die out completely here, but it lingers on.

I also have a gun which de materializes people. It shoots jets of fluorosulfonic acid.

Or does that not count?

Maybe because 90% of American wouldn't know how to use it.

Yes....I went there.

That's nine-tenths, incidentally.

I want 9/10s of America, Every Citizens body apart from their brain.

I want to stuff them into perfect rectangles, their brains jam up the grinder blades....

You're right, it isn't easier. Gotta love Americans aversion to learning something new. It may not be easier to you, but to me and many others that have taken the time to learn it, the metric system makes more sense and is much easier to use.

I can go out right now and ask a multitude of people what temperature that water boils and most will have no clue. So what is easier? 100 degree celsius or 212 fahrenheit?

If you look at it as a whole, it is a lost easier to understand over what we currently use. As for the time, it does take getting used to but with in a few days you easily adapt.

I'm with Jaffa Cake on this one...

To use the 24 hr clock, I ignore the first one (or two), subtract 2 from the next number (If it goes to zero, I then add a one back in front and then if the number doesn't make sense just assume it's an 11. 'Last Orders' in old money)

Ish times are much better. For example "Oooh, I don't know - how about 7'ish at the bar..."

Americans have enough to worry about.

Your country also probably sees metric in widespread use. If you see it every day of your life everywhere of course it will be easier. That's why Americans keep using miles, gallons, and Farenheit... because that's what we're used to. The system works fine, and there's no reason to change it.

Easier? If you grow up with learning that 100 C is water's boiling point, then that will be easier. If you grow up learning 212 F, that will be easier.

"The United States" seems to disagree, otherwise we would have switched a long time ago.

I believe you would then legally own America, what with possession being nine-tenths of the law and everything.
