What is Fahrenheit?

Fahrenheit is a temperature scale named after the German physicist D. G. Fahrenheit.

In Fahrenheit, the freezing point of water is 32 degrees °F and the boiling point 212 °F. That puts the boiling point and freezing point of water 180 degrees apart.

Today, the Fahrenheit scale is used mainly in the United States.

What is Celsius / Centigrade ?

Celsius (Centigrade) is a temperature scale named after the Swedish astronomer Anders Celsius.

Zero (0 °C) on the Celsius scale is approximately the freezing point of water and 100 °C is approximately the boiling point of water.

What is Kelvin?

The Kelvin temperature scale developed by scientists is based on Celsius/Centigrade.

A key fact about the Kelvin scale is that it has no negative numbers. Therefore, zero on the Kelvin scale is absolute zero. Zero on the Kelvin scale is the point at which all molecular motion stops.

What does it all mean?

It means that when people in metric countries say, "It's freezing outside, it's 1"... that means it's a balmy 33.8 in the USA!
