Why is COLD temperature in Fahrenheit and HOT temps in Celsius?

Answer 1

Are you serious? Every possible temperature is in both Fahrenheit and Celsius whether it's hot or cold. Depends where you live if you use F or C.

Answer 2

I suppose that it is psychological. Minus 2 degrees Celsius sounds colder than 28 degrees Fahrenheit although they are both the same. Likewise 28 degrees Celsius doesn't so unbearable hot as 82 degrees Fahrenheit. Having said that, if the temperature is minus 40 degrees, it doesn't matter which scale you use as that is the temperature for which the value is the same in both Celsius and Fahrenheit.

Answer 3

Dude, like metric system, Celsius are an standard all around the world. Only few exceptions try to survive usinf Fahrenheit.

Kelvin is the most used temp reference within labs but its harder to get it once its limits are not linkled to common sense as Water (Celsius Temp) 0 you are talking about when water become Ice.

Usually, you use only one to cold or hot temperatures. Perhaps you are receiving information from another country.

Hardly you can find countries using both temperatures. You have only one standard.

Answer 4

Actually hot and cold is all very relative and you can use the Fahrenheit or Celsius scale. Fahrenheit is really only used in the general American public. My favorite is the Kelvin temperature scale. At 0 Kelvin, it is so cold that all atomic motions stops. That is just theoretical, since scientists can't create conditions cold enough for that to happen. 0 Kelvin is -459.69 degrees Fahrenheit!

Answer 5

I think you have that backwards LOL! Hot temps are Fahrenheit & cold are below zero, or just recorded 20 degrees, etc. Some countries use celsius only, some both.

Answer 6

I presume you mean when people are talking?

I think it's 'cos lower number suggest lower temperatures and therefore it sounds cold and higher numbers suggest higher temperatures and therefore it sounds hot.

Which sounds hotter: 86°F or 30°C?
Which sounds cooler: 37°F or 3°C?

I know these temperatures are interchangeable but it is perceptions that matter.

Oh, and Celcius and Centigrade are totally interchangeable words. They mean the same thing.

In case you are interested, the following is the formula:
Celsius to Fahrenheit: °F = °C × 1.8 + 32
Fahrenheit to Celsius: °C = (°F – 32) / 1.8

Answer 7

Good point, We are supposed to be metric and use Celsius for most things on TV weather etc. but when it's hot you always hear people saying "It's over a hundred" not "it's 27 degrees" (or whatever). By contrast in cold weather we hear "It's minus 5" never "it's 39 degrees" for example.

Good point, although you've stated it the wrong way round.

Answer 8

34 degrees celsius is a really hot day where i come from but its probably a quite warm day in someplaces? And 3 degrees would be really really cold. Almost freezing temperatures. Water boils at 100 C and it freezes at 0 C if that scale is any help.

Answer 9

If it's cold and you use farenheit, then it appears warmer because the numbers are higher, same way if its hot, and you use celsius they appear lower. I'ts currently 30 degrees here. Now if that was Farenheit, it would be below freezing, but in Celsius it very hot.

Answer 10

hmm yeah everybody else here is right but because as temperature is relative celsius is the correct one to use for humans because it is based on the freezing point of water being zero and the boiling point being 100'C and because humans are 60% water it seems that celsius would be more relevant too use too describe hot and cold to humans because as they said hot and cold is relative to the observer
