How to Convert kcal/(h·m·°C) to BTU/(h·ft·°F)
- 1 kcal/(h·m·°C) = 0.6719689751 BTU/(h·ft·°F)
- 1 BTU/(h·ft·°F) = 1.488163944 kcal/(h·m·°C)
- Example: convert 15 kcal/(h·m·°C) to BTU/(h·ft·°F): 15 kcal/(h·m·°C) = 15 × 0.6719689751 BTU/(h·ft·°F) = 10.07953463 BTU/(h·ft·°F)
Reference conditions. kcal/(h·m·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
BTU/(h·ft·°F) = kcal/(h·m·°C) × 0.6719689751395
or BTU/(h·ft·°F) = kcal/(h·m·°C) ÷ 1.48816394357
Derivation from SI units:
- 1 kcal_IT/(h·m·°C) = 4186.8 J ÷ (3600 s × 1 m × 1 K) = 1.163 W/(m·K) (exact)
- 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/(h·m·°C) = 1.163 W/(m·K) ÷ 1.730734666371 W/(m·K) per BTU/(h·ft·°F) = 0.6719689751395 BTU/(h·ft·°F)
Both units are defined exactly, so the factor is exact. kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius; BTU/(h·ft·°F) definition: BTU per hour foot degree Fahrenheit.
Worked examples
- A reading of 0.05 kcal/(h·m·°C) converts to 0.03359844876 BTU/(h·ft·°F).
0.05 kcal/(h·m·°C) × 0.6719689751 = 0.03359844876 BTU/(h·ft·°F) - A value of 1.2 kcal/(h·m·°C) is 0.8063627702 BTU/(h·ft·°F).
1.2 kcal/(h·m·°C) × 0.6719689751 = 0.8063627702 BTU/(h·ft·°F)
