How to convert kelvins per kilowatt to Fahrenheit degree hours per Btu IT
These units describe thermal resistance K/W. Area-normalized insulation R-values in m²·K/W need a known area and are not interchangeable with whole-object resistance.
Use x for the value in K/kW, b for the intermediate value in K/W, and y for the result in °F·h/Btu IT.
°F·h/Btu IT = K/kW × 0.001 ÷ 1.8956342406266344
Worked examples
10 K/kW ≈ 0.0052752792631 °F·h/Btu IT
Step 1: (10 × 0.001) ≈ 0.01 K/W.
Step 2: 0.01 ÷ 1.89563424063 ≈ 0.0052752792631 °F·h/Btu IT.20 K/kW ≈ 0.0105505585262 °F·h/Btu IT
Step 1: (20 × 0.001) ≈ 0.02 K/W.
Step 2: 0.02 ÷ 1.89563424063 ≈ 0.0105505585262 °F·h/Btu IT.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kelvins per kilowatt
Kelvins per kilowatt (K/kW) measures thermal resistance under the conventions above. The base value in K/W is (x × 0.001), where x is the numerical value in K/kW. Factors shown here are rounded for display; calculations use the stored factor.
About Fahrenheit degree hours per Btu IT
Fahrenheit degree hours per Btu IT (°F·h/Btu IT) measures thermal resistance under the conventions above. The base value in K/W is (x × 1.89563424063), where x is the numerical value in °F·h/Btu IT. Factors shown here are rounded for display; calculations use the stored factor.
