U-factor (BTU/h·ft²·°F) to U-factor (W/m²·K)

Convert U-factor (BTU/h·ft²·°F) to U-factor (W/m²·K), with the math shown step by step.

Watts per square meter-kelvin
0.91 W/(m²·K)

0.16 BTU/(h·ft²·°F) = 0.91 W/(m²·K)

Also equals

How it works

W/(m²·K) = BTU/(h·ft²·°F) × 5.67826334

One BTU per hour-square foot-degree Fahrenheit is about 5.67826334 watts per square meter-kelvin, so multiplying by 5.67826334 turns BTU per hour-square foot-degree Fahrenheit into watts per square meter-kelvin. For example, 0.3 BTU/(h·ft²·°F) is about 1.703 W/(m²·K).

  1. Multiply by 5.67826334 0.16 × 5.67826334 = 0.91 W/(m²·K)
