Kelvin scale
absolute scale

He is widely known for developing the Kelvin scale of absolute temperature measurement.

Unlike a chromaticity diagram, the Kelvin scale reduces the light source's color into one dimension.

T is temperature, which is measured in Kelvin scale.

The Kelvin scale, however, is used for Mach number calculations.

Hence, the Kelvin scale is a ratio scale.

Recrystallization generally begins when temperatures reach above half the melting point of the mineral on the Kelvin scale.

In the scientific world, thermodynamic temperature is usually measured using the Kelvin scale.

The Kelvin scale is defined by a specific relationship between the pressure of a gas and the temperature.

On the Kelvin scale, 0 is absolute zero and water freezes at about 273 degrees.

("K" is reserved for a unit of temperature on the Kelvin scale.)
