What is the difference between Celsius and Fahrenheit?

Answer 1

It's all a matter of scale.

Both have a linear progression. The biggest difference is that the Celsius scale was based on the freezing point of water and the boiling point of water. The Fahrenheit scale, however, was based on the freezing point of water and the average body temperature. He was off a little bit on that one.

Here is an overview of some measurements:
Freezing point of water: 0C 32F
Boiling point of water: 100C 212F
Average body temperatue: 36.8C 98.24F

Zero on the Fahrenheit scale represents the temperature produced by the mixing of equal weights of snow and common salt.

°Fahrenheit °Celsius
Boiling point of water 212° 100°
Freezing point of water 32° 0°
Absolute zero –459.6° –273.1°

Absolute zero is theoretically the lowest possible temperature, the point at which all molecular motion would cease.

To convert Fahrenheit to Celsius (Centigrade), subtract 32 and divide by 1.8.

To convert Celsius (Centigrade) to Fahrenheit, multiply by 1.8 and add 32.

Kelvin Scale

Answer 3

A degree Celsius (°C) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701-1744), who first proposed a similar system in 1742. From around 1750 the scale was known as the Centigrade scale, and though it was renamed after Celsius in 1948, the older name is still in widespread use. One reason for the change was that the term centigrade was in use in continental Europe as a measure of plane angle equal to one ten-thousandth part of a right angle. Fahrenheit is a temperature scale named after the German physicist Gabriel Fahrenheit (1686–1736), who proposed it in 1724. In this scale, the freezing point of water is 32 degrees Fahrenheit (written "32 °F"), and the boiling point is 212 degrees, placing the boiling and melting points of water 180 degrees apart. Thus the unit of this scale, a degree Fahrenheit, is 5/9ths of a kelvin (which is a degree Celsius), and negative 40 degrees Fahrenheit is equal to negative 40 degrees Celsius. The Celsius scale sets 0.01 °C to be at the triple point (the temperature and pressure at which three phases [gas, liquid, and solid] of that substance may coexist in thermodynamic equilibrium) of water and a degree Celsius to be 1/273.16 of the difference in temperature between the triple point of water and absolute zero. Until 1954 the scale was defined with the freezing point of water at 0 °C and the boiling point at 100 °C at standard atmospheric pressure. This definition is still a close approximation to the modern definition.

Answer 4

To convert Celsius to Fahrenheit multiply by 1.8 and than add 32.

100 X 1.8 + 32 = 212

100 degrees C and 212 degrees F are the boiling point of water.

-40 C = -40 F.

To convert Fahrenheit To Celsius reverse the order. F - 32 / 1.8 = C

Answer 5

The Celcius scale was developed for the Metric system with 100 degrees between boiling and freezing of water. Water freezes at 0 degrees C, and boils at 100 C. The Fahrenheit scale has 180 degrees between boiling and freezing of water. 32 F is freezing, 212 F is boiling. By comparing these you can see that Celcius degrees must be bigger. 9/5 bigger. The formula for changing between the two uses this fraction and the point that F starts at 32. Scientists use the Kelvin scale which has the same size degrees as C but starts at absolute zero, -273C.

Answer 6

Celsius starts with a mean reading of zero Fahrenheit starts at 32 degrees the temp at witch water freezes.

Answer 7

Celsius is based on varying temperatures of water and it is much more modern scale. Water freezes at 0 degrees Celsius and boils at 100 degrees Celsius, whereas Farenheit is a much older scale has no relationship with any freezing or boiling points of water. In Farenheit water freezes at 32 degrees and boils at 212 degrees. Celsius is based on water whereas Farenheit is much older and based on nothing.

Answer 8

ration of F to C is 9:5
