How to Convert Kilocalorie per Kilogram to BTU per Pound
- 1 kcal/kg = 1.8 BTU/lb
- 1 BTU/lb = 0.5555555556 kcal/kg
- Example: convert 15 kcal/kg to BTU/lb: 15 kcal/kg = 15 × 1.8 BTU/lb = 27 BTU/lb
Reference conditions. kcal/kg: International Table calorie (4.1868 J).
Formula
BTU/lb = kcal/kg × 1.8
Derivation from SI units:
- 1 kcal_IT/kg = 4186.8 J/kg.
- 1 BTU_IT/lb = 1055.05585262 J ÷ 0.45359237 kg = 2326 J/kg exactly.
- 1 kcal/kg = 4186.8 J/kg ÷ 2326 J/kg per BTU/lb = 1.8 BTU/lb
Both units are defined exactly, so the factor is exact. Kilocalorie per Kilogram definition: kilocalorie per kilogram; BTU per Pound definition: BTU per pound.
Worked examples
- A reading of 100 kcal/kg converts to 180 BTU/lb.
100 kcal/kg × 1.8 = 180 BTU/lb - A value of 3500 kcal/kg is 6300 BTU/lb.
3500 kcal/kg × 1.8 = 6300 BTU/lb
