kW/(m²·K)toBTU/(hr·ft²·°F)

Convert kilowatts per square metre-kelvin (kW/(m²·K)) to British thermal units per hour-square foot-Fahrenheit (BTU/(hr·ft²·°F)).

Factor1 kW/(m²·K) = 176.1102 BTU/(hr·ft²·°F)

Converter

kW/(m²·K)

Accepts numbers or expressions, e.g. 150 + 14.7

Result
176.11BTU/(hr·ft²·°F)

Rendered to 6 significant figures.

Formula

Formula
BTU/(hr·ft²·°F) = kW/(m²·K) × 176.1102

Multiply any value in kilowatts per square metre-kelvin by 176.1102 to obtain the value in British thermal units per hour-square foot-Fahrenheit.

Worked example

Convert 1 kW/(m²·K) to BTU/(hr·ft²·°F).

  1. 01Start with 1 kW/(m²·K).
  2. 02Multiply by the conversion factor: 1 × 176.1102 = 176.11 BTU/(hr·ft²·°F).
Result1 kW/(m²·K) = 176.11 BTU/(hr·ft²·°F)

FAQ

What is the conversion factor from kW/(m²·K) to BTU/(hr·ft²·°F)?
1 kW/(m²·K) equals 176.1102 BTU/(hr·ft²·°F). To convert, multiply the value in kilowatts per square metre-kelvin by 176.1102.
How do I convert 1 kW/(m²·K) to BTU/(hr·ft²·°F)?
1 kW/(m²·K) = 176.11 BTU/(hr·ft²·°F). For any value, multiply by 176.1102.
How do I convert BTU/(hr·ft²·°F) back to kW/(m²·K)?
Divide by the same factor — or equivalently, multiply by 0.005678263. So 1 BTU/(hr·ft²·°F) = 0.00567826 kW/(m²·K).
When would I need to convert kilowatt per square metre-kelvin to British thermal unit per hour-square foot-Fahrenheit?
Heat-transfer coefficient conversions between kW/(m²·K) and BTU/(hr·ft²·°F) are needed in heat-exchanger sizing, boiler and condenser design, and HVAC calculations. W/(m²·K) is standard in SI engineering, and BTU/(hr·ft²·°F) is common in US heat-exchanger correlations and vendor literature.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
