# What is the unit of the coefficient of thermal conductivity K?

The unit of the coefficient of thermal conductivity K is Wm-1K-1.

Thermal conductivity of a material is defined as the measure of how quickly heat energy is transferred from one end to the other end.

The rate at which heat gets transferred depends on the value of the K. Lower the value of K, slower will be the conduction.

The dimensional formula of thermal conductivity is MLT-3K-1.
