How the Calculation Works (Linear Scaling)
Formula:
IT BTU per Hour Square Foot Degree Fahrenheit = Watt per Square Meter Kelvin / 5.678263
Substitution:1 / 5.678263
Calculated Result:0.1761 Btu_IT/(h·ft²·°F)
Since 1 IT BTU per Hour Square Foot Degree Fahrenheit = 5.678263 Watts per Square Meter Kelvin, divide the value in Watts per Square Meter Kelvin by 5.678263.
Standard Ratio Factor:1 W/(m²·K) = 0.17611 Btu_IT/(h·ft²·°F)
