How to Convert Kilowatt per Square Metre Kelvin to BTU/(h·ft²·°F)
- 1 kW/(m²·K) = 176.1101837 BTU/(h·ft²·°F)
- 1 BTU/(h·ft²·°F) = 0.005678263341 kW/(m²·K)
- Example: convert 15 kW/(m²·K) to BTU/(h·ft²·°F): 15 kW/(m²·K) = 15 × 176.1101837 BTU/(h·ft²·°F) = 2641.652755 BTU/(h·ft²·°F)
Formula
BTU/(h·ft²·°F) = kW/(m²·K) × 176.1101836823
Derivation from SI units:
- 1 kW/(m²·K) = 1000 W/(m²·K)
- 1 BTU_IT/(h·ft²·°F) = 1055.05585262 J ÷ (3600 s × 0.09290304 m² × 5/9 K) = 5.678263341 W/(m²·K) (exact)
- 1 kW/(m²·K) = 1000 W/(m²·K) ÷ 5.678263341113 W/(m²·K) per BTU/(h·ft²·°F) = 176.1101836823 BTU/(h·ft²·°F)
Both units are defined exactly, so the factor is exact. Kilowatt per Square Metre Kelvin definition: kilowatt per square metre kelvin; BTU/(h·ft²·°F) definition: BTU per hour square foot degree Fahrenheit.
Worked examples
- A reading of 2 kW/(m²·K) converts to 352.2203674 BTU/(h·ft²·°F).
2 kW/(m²·K) × 176.1101837 = 352.2203674 BTU/(h·ft²·°F) - A value of 10 kW/(m²·K) is 1761.101837 BTU/(h·ft²·°F).
10 kW/(m²·K) × 176.1101837 = 1761.101837 BTU/(h·ft²·°F)

Where it's used
Kilowatts per Square Metre Kelvin are used for shell-and-tube and plate heat exchangers, while BTU per hour square foot degree Fahrenheit appear in US window and building U-factors (NFRC, ASHRAE). Both measure heat transfer coefficient (h) and thermal transmittance (U-value), so the conversion is a fixed factor.
