How to Convert Watt per Centimetre Kelvin to BTU/(h·ft·°F)
- 1 W/(cm·K) = 57.77893165 BTU/(h·ft·°F)
- 1 BTU/(h·ft·°F) = 0.01730734666 W/(cm·K)
- Example: convert 15 W/(cm·K) to BTU/(h·ft·°F): 15 W/(cm·K) = 15 × 57.77893165 BTU/(h·ft·°F) = 866.6839748 BTU/(h·ft·°F)
Formula
BTU/(h·ft·°F) = W/(cm·K) × 57.7789316543
Derivation from SI units:
- 1 W/(cm·K) = 100 W/(m·K)
- 1 BTU_IT/(h·ft·°F) = 1055.05585262 J ÷ (3600 s × 0.3048 m × 5/9 K) = 1.730734666 W/(m·K) (exact)
- 1 W/(cm·K) = 100 W/(m·K) ÷ 1.730734666371 W/(m·K) per BTU/(h·ft·°F) = 57.7789316543 BTU/(h·ft·°F)
Both units are defined exactly, so the factor is exact. Watt per Centimetre Kelvin definition: watt per centimetre kelvin; BTU/(h·ft·°F) definition: BTU per hour foot degree Fahrenheit.
Worked examples
- A reading of 1 W/(cm·K) converts to 57.77893165 BTU/(h·ft·°F).
1 W/(cm·K) × 57.77893165 = 57.77893165 BTU/(h·ft·°F) - A value of 2.37 W/(cm·K) is 136.936068 BTU/(h·ft·°F).
2.37 W/(cm·K) × 57.77893165 = 136.936068 BTU/(h·ft·°F)
