Formula
kcal/(h·m·°C) = BTU/(h·ft·°F) × 1.48816394357
Derivation from SI units:
- 1 BTU_IT/(h·ft·°F) = 1055.05585262 J ÷ (3600 s × 0.3048 m × 5/9 K) = 1.730734666 W/(m·K) (exact)
- 1 kcal_IT/(h·m·°C) = 4186.8 J ÷ (3600 s × 1 m × 1 K) = 1.163 W/(m·K) (exact)
- 1 BTU/(h·ft·°F) = 1.730734666371 W/(m·K) ÷ 1.163 W/(m·K) per kcal/(h·m·°C) = 1.48816394357 kcal/(h·m·°C)
Both units are defined exactly, so the factor is exact. BTU/(h·ft·°F) definition: BTU per hour foot degree Fahrenheit; kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius.
Worked examples
- A reading of 0.1 BTU/(h·ft·°F) converts to 0.1488163944 kcal/(h·m·°C).
