| Unit | Equivalent measurements |
|---|
| Celsius scale | This scale sets the normal freezing point of water to 0 degrees Celsius and the normal boiling point of water to 100 degrees Celsius. Formerly called the Centigrade scale. |
|---|
| Kelvin scale | This scale sets the lowest obtainable temperature (absolute zero = the temperature at which all molecular motion completely ceases) to 0 degrees. A change of one degree Celsius = a change of one Kelvin, but a Celsius temperature is never equal to a Kelvin temperature. There are no negative temperatures in the Kelvin scale. Note: simply use "Kelvin" or "Kelvins", not "degrees Kelvin" when using this unit. |

| Fahrenheit scale | This scale sets the freezing point of water to 32 degrees F & the boiling point of water to 212 degrees F. 180 Degrees inbetween (1/2 a circle). |
