What about Celcius?

Kelvin!

Rankine!

Neither.

They are both completely arbitrary constructs.

Almost all units of measure are.
At least C is equivalent to Kelvin, with only the Zero point shifted to 273 K

I thought Celcius was based on the frezzing and boiling point of water. 0 and 100 or is that just a coincidence?

Not the Cubit.

I like the Metric system, in which I include the centigrade scale for temperature, but I grew up with Farenheit and feet, and it's hard to drop the old measures. I keep threatening to throw out all my tape measures and rulers and go metric, but it's hard to do that in this country.

All day long I look at Centigrade temps on the weather readouts at work and try to not convert them into Farenheit in my head so I know if I need a jacket when I go outside.

Maybe we should just convert to Kelvin and be done with it. Hmmm, water freezes at 273 degrees and boils at 373. Does that seem to roll off the tongue? How about "Nice day out there. It's almost 300 degrees."?

It only does that at "standard atmospheric pressure", which I can assure you is also pretty arbitrary if you live anywhere but sea level or the pressure is higher or lower than standard.

Tell me what temperature water boils at in Denver.

I find the following temperature scale works just fine

Fucking cold
Cold
Warm
Hot
Fucking hot

It's beautiful here. A nice breezy 530 Ra.
ahhhh...gotta love 'winter'.

Thats easy, This time of year water in Denver doesn't boil. Thats because, as you can see on my tempature scale, Denver is fucking cold! Therefor water in Denver is ice.

Oh yeah I forgot to mention that the melting point of ice remains constant regardless.

My point is that this unit of measure is not arbitrary. It was developed based on the freezing and boiling point of water, so be it at MSL.

Actually, it doesn't.

In fact, there is a certain temperature and pressure at which the three states; ice, water and vapor exist simultaneously. Move either pressure or temperature just a tiny fraction of a degree (any degree you want to use really) and it definitively becomes one of the three states, but at that temperature and pressure it would be impossible to say.

This is called the triple point.

If I was designing a universal standard, I might consider using the triple point of water as one datum point, but then . . . what makes water so special?




(As you may have guessed, this IS one of my favorite ultra-geek topics because it makes people's heads explode.)

It's just a brand name - like Tissue vs Kleenex . . .

Don't forget that clouds often contain super cooled H2O in liquid droplets that freezes on impact with aircraft. So there's liquid water well below O Cent.

That would be the temperature where the molecules become so excited that they rapidly move and the result is that it starts to dissipate into the air

I always wondered why so many Americans keep saying "centigrade".

Someone must keep teaching that term??

The scale was renamed "Celsius", in 1948 -- so it isn't like a change that just happened.

I'll stick to my universal standard.

If the water is frozen - It's fucking cold

If the water is boiling - It's fucking hot

Well centigrade still works if you look at the origin of the word. Centi - 100, grade - scale = scale of 100.

there is a scale of 100 units at which water remains in a liquid form.

And here's one of my all-time favorites;

Take a bowl of room temperature water and put it in a vacuum chamber. Seal the chamber and start pumping the air out.

At a certain point, the water begins to boil. Then if you keep doing it, while the water is boiling, it turns into ice.

I have a freezer. It makes ice too. No vacuum chamber required.

Although now that I have read this I could see myself half way thru a bottle of bourbon, having just run out of ice, getting a bowl of water and a vacuum cleaner. Loudly procaiming "don't worry, I read about this on DZ.com, I know what I'm doing"

Just marry a gold digger, ice forms naturally when she is in the same room.

It's considered the Universal Solvent and life on Earth would not exist without, that's what makes it so special.

And as mentioned before it's not arbitrary, there's a reason it was instituted, and the reason is at STP it indicates the freezing and boiling points of water.
It becomes the standard.
Saying it's a "completely arbitrary" measure is asinine and ignorant especially for someone professing expertise in the field
