Scientists use the Kelvin temperature scale.


Scientists use the Kelvin scale, because a temperature of 0 K represents absolute zero, the coldest temperature that is physically possible. All Kelvin temperatures are therefore positive numbers.

Scientists also use the Celsius scale for routine measurements, but they often have to convert the temperatures to the Kelvin scale for use in their calculations.

The Celsius scale is convenient for scientists, because a temperature change of 1 °C is the same size as a change of 1 K.

The two scales differ by 273.15 degrees: 0 °C = 273.15 K

To convert from one scale or another, all that scientists have to do is add or subtract 273.15 degrees.
