kelvin and fahrenheit scales? What are the differences and similarities to a celsuis temperature scale?

Question

Where is each of them used??

Answer 1

The fahrenheit scale is most frequently used for everyday weather in the US. The major problem with this scale, however is that the size of the degrees are very small. Having a freezing point of water as 32F and a boiling point of water as 212F is a wide range to have to cover.

The celcius scale is better as it was based on the boiling and freezing point of water. The freezing point of water on the celcius scale is 0C and boiling point is 100C giving the most used range of temperatures limited to only 100 degrees. However, for scientific purposes it can be quite cumbersome.

The scientific term "absolute zero" defines the coldest point that matter can get so that there is no molecular movement. On the celcuis scale this is -273C and on the fahrenheit scale it is -459F.

To alleviate scientists having to deal with negative integers so much when dealing with very cold matter (back in the days before calculators and computers were as common as they are today) the Kelvin scale was developed based on absolute zero. Absolute zero completely eliminates negative numbers by assigning 0K as absolute zero. Just to give you an idea, on a hot summer's day of 90 degrees fahrenheit, it is 305 degrees Kelvin.
In the winter, when it is a mere 10 above (fahrenheit) it is 261K and -12C

Answer 2

Kelvin is used in Chemistry Physics and many branches of basic scientific calculations as zero on the Kelvin scale is considered as absolute zero. The Kelvin scale is the same as the Celsius scale, but zero of Celsius scale is 273 on Kelvin scale. To find out temperature on Kelvin scale , just add 273 to the Celsius temperature.
Fahrenheit is a much smaller scale than Celsius. Zero on Celsius is 32 on Fahrenheit and 100 on Celsius is 232 on Fahrenheit, that is why there are 180 degrees between the boiling and freezing point of water, where as in Celsius, it's only 100. Fahrenheit was much popular in medical science and some of the British reports. However, the international science community uses Celsius.

Answer 3

The Kelvin scale is the same as the Celsius scale. Kelvin is used in chemistry calculations because zero on the Kelvin scale is absolute value. If they used Celsius, they would have to deal with negative numbers, which would throw off any calculations. To find how hot it is in Kelvin, just add 273 to the Celsius temperature.

Fahrenheit is a much smaller scale than Celsius. On it, it's 180 degrees between the boiling and freezing point of water, where as in Celsius, it's only 100. It perplexes me that we don't use Fahrenheit internationally because it is more accurate in measuring heat. However, the international science community uses Celsius, so we must convert here in the US. It's some weird formula that I can't recall off the top of my head, but most hand-held electronic devices will have a converter on them.

Answer 4

All those countries that once used fahrenheit now use celsius except for the USA. They will have to fall in line eventually. The rest of the world doesn't understand fahrenheit. Celsius is a far more useful scale as it can be used directly in calculations with metric units and has the same sized degrees as the Kelvin scale. Fahrenheit will disappear eventually along with miles, gallons and pounds - all of which only survive in the USA.

Answer 5

Celsius stages are an identical era as Kelvins; they only initiate at distinctive numbers. 0 Celsius is 273 Kelvin. a hundred stages Celsius is 373 Kelvin. Fahrenheit has a distinctive era between stages. consequently, to transform 273 Kelvin to Fahrenheit...you may first comprehend that it rather is 0 stages Celsius....then use the formulation stages Fahrenheit = 9/5 stages Celsius plus 32.

Answer 6

Kelvin is mostly used in physics and chemistry in gas laws, free energy equations, etc. The Kelvin scale is pretty similar to the Celsius in that:

Kelvin = degrees Celsius + 273

Fahrenheit is sadly really only used in the USA and not really anywhere else. It isn't used in science at all except perhaps junior high science classes. Too bad the United States is too stuck up to change to the units the rest of the world uses. :(

Answer 7

Celcius Or Centigrade - Water boils at 100 and freezes at 0.
Fahreneit - Water [Under standard conditions] at 212 and freezes at 32. Kelvin - Water boils at 373.15 K and freezes at 273.15 K.
CONVERT
Fahreneit into Centigrade: Subtract 32, Multiply by 5, and Divide by 9. Centigrade into Fahreneit: Multiply by 9, Divide by 5, and Add 32. Centigrade into Kelvin: Add 273.15.
