# Ethylene - Thermal Conductivity vs. Temperature and Pressure

## Online calculator, figures and table showing thermal conductivity of ethylene, also called ethene or acetene, C2H4, at varying temperature and pressure - Imperial and SI 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].

### Online Ethylene Thermal Conductivity Calculator

The calculator below can be used to estimate the thermal conductivity of ethylene at given temperature and atmospheric pressure.

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).

Temperature

Choose the actual unit of temperature: °C  °F  °R

as well as thermal conductivity o For thermal conductivity of construction materials, see related documents at the bottom of the page.
