Methane - Thermal Conductivity vs. Temperature and Pressure

Calculator for estimating the thermal conductivity of gaseous methane at given temperatures and pressures. Thermal conductivity is a material property describing the ability to conduct heat. This tool provides output in multiple units: mW/(m K), Btu(IT)/(h ft °F), (Btu(IT) in)/(h ft² °F) and kcal(IT)/(h m K).
