Carbon Dioxide - Thermal Conductivity vs. Temperature and Pressure

Thermal conductivity calculator for carbon dioxide at given temperatures and pressures. Thermal conductivity is the ability of a material to conduct heat, measured in W/(m K) or other units. This tool provides thermal conductivity values for CO2 in various states (gas, liquid, supercritical) across different temperature and pressure conditions.

Thermal Conductivity Units Conversion

Common Conversions:

  • 1 W/(m·K) = 0.5779 Btu(IT)/(ft·h·°F) = 0.04815 Btu(IT)/(in·h·°F) = 0.85984 kcal/(m·h·°C)
  • 1 Btu(IT)/(ft·h·°F) = 1.731 W/(m·K)
  • 1 kcal/(m·h·°C) = 1.163 W/(m·K)

Notes:

  • Thermal conductivity is the ability of a material to conduct heat
  • Units: W/(m·K) in SI system, Btu/(h·ft·°F) in Imperial system, mW/(m·K), kcal(IT)/(h·m·K), Btu(IT)/(h·ft·°F), (Btu(IT)·in)/(h·ft²·°F)
  • Data provided for various states: Gas, Liquid, and Supercritical phase
  • Measurements at different pressures: 0.1, 1, 5, 10, 100, and 1000 bara
