# Nitrogen - Thermal Conductivity vs. Temperature and Pressure

## Online calculator, figures and tables showing thermal conductivity of nitrogen, N2, at varying temperarure and pressure, SI and Imperial units.

Thermal conductivity is a material property that describes ability to conduct heat. Thermal conductivity can be defined as

"the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"

The SI unit used for thermal conductivity is [W/m K], while a common Imperial unit is [Btu/h ft °F].
