Butane - Thermal Conductivity vs. Temperature and Pressure

Sponsored Links

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).

The thermal conductivity of butane depends on temperature and pressure as shown in the figures and tables below.

Online Butane Thermal Conductivity Calculator

The calculator below can be used to estimate the thermal conductivity of butane at given temperature and atmospheric pressure.
Note! Butane boiling point at atmospheric pressure is -0.8°C / 30.5°F, and hence, there is a shift in conductivity at that temperature.

The output thermal conductivity is given as mW/(m K), Btu(IT)/(h ft °F), (Btu(IT) in)/(h ft2°F) and kcal(IT)/(h m K).
