### Fahrenheit

Fahrenheit is a thermodynamic temperature scale where the freezing point of water is 32 degrees Fahrenheit (° F) and the boiling point is 212 ° F (at normal pressure). This means that the boiling and freezing points of water are exactly 180 degrees apart. Therefore, one degree on the Fahrenheit scale is 1/180 of the interval between the freezing and boiling points of water. Absolute zero is defined as -459.67 ° F.

A temperature difference of 1 ° F corresponds to a temperature difference of 0.556 ° C.

### Celsius

Although initially defined by the freezing point of water (and later the melting point of ice), the Celsius scale is officially derived from the Kelvin scale.

Zero on the Celsius scale (0 ° C) equals 273.15 K, with a temperature difference of 1 ° C equivalent to a difference of 1 K, so the size of the unit is the same on each scale. This means that 100 ° C, which was previously defined as the boiling temperature of water, now corresponds to 373.15 K.

The Celsius scale is an interval system, not a ratio system, which means that it follows a relative but not an absolute scale. This can be seen from the fact that a temperature interval between 20 ° C and 30 ° C is the same as between 30 ° C and 40 ° C, but 40 ° C does not have twice the air heat energy as 20 ° C.

A temperature difference of 1 ° C corresponds to a temperature difference of 1.8 ° F.
