How to convert kelvins per watt to Celsius degrees per watt
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/W, b for the intermediate value in K/W, and y for the result in °C/W.
°C/W = K/W
Worked examples
10 K/W ≈ 10 °C/W
Step 1: (10 × 1) ≈ 10 K/W.
Step 2: 10 ÷ 1 ≈ 10 °C/W.20 K/W ≈ 20 °C/W
Step 1: (20 × 1) ≈ 20 K/W.
Step 2: 20 ÷ 1 ≈ 20 °C/W.
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 watt
Kelvins per watt (K/W) measures thermal resistance under the conventions above. The base value in K/W is (x × 1), where x is the numerical value in K/W. Factors shown here are rounded for display; calculations use the stored factor.
About Celsius degrees per watt
Celsius degrees per watt (°C/W) measures thermal resistance under the conventions above. The base value in K/W is (x × 1), where x is the numerical value in °C/W. Factors shown here are rounded for display; calculations use the stored factor.
