How to convert joules per kilogram kelvin to Btu IT per pound Fahrenheit degree
Use the same thermodynamic convention before comparing values: constant-pressure and constant-volume heat capacities can differ. Temperature factors here are intervals, without offsets.
Use x for the value in J/(kg·K), b for the intermediate value in J/(kg·K), and y for the result in Btu IT/(lb·°F).
Btu IT/(lb·°F) = J/(kg·K) ÷ 4186.799999999999
Worked examples
10 J/(kg·K) ≈ 0.00238845896627 Btu IT/(lb·°F)
Step 1: (10 × 1) ≈ 10 J/(kg·K).
Step 2: 10 ÷ 4186.8 ≈ 0.00238845896627 Btu IT/(lb·°F).20 J/(kg·K) ≈ 0.00477691793255 Btu IT/(lb·°F)
Step 1: (20 × 1) ≈ 20 J/(kg·K).
Step 2: 20 ÷ 4186.8 ≈ 0.00477691793255 Btu IT/(lb·°F).
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 Joules per kilogram kelvin
Joules per kilogram kelvin (J/(kg·K)) measures specific heat capacity under the conventions above. The base value in J/(kg·K) is (x × 1), where x is the numerical value in J/(kg·K). Factors shown here are rounded for display; calculations use the stored factor.
