How to Convert Kilocalorie per Kilogram to Kilowatt-hour per Kilogram
- 1 kcal/kg = 0.001163 kWh/kg
- 1 kWh/kg = 859.8452279 kcal/kg
- Example: convert 15 kcal/kg to kWh/kg: 15 kcal/kg = 15 × 0.001163 kWh/kg = 0.017445 kWh/kg
Reference conditions. kcal/kg: International Table calorie (4.1868 J).
Formula
kWh/kg = kcal/kg × 0.001163
or kWh/kg = kcal/kg ÷ 859.845227859
Derivation from SI units:
- 1 kcal_IT/kg = 4186.8 J/kg.
- 1 kWh/kg = 3.6 × 10⁶ J/kg.
- 1 kcal/kg = 4186.8 J/kg ÷ 3600000 J/kg per kWh/kg = 0.001163 kWh/kg
Both units are defined exactly, so the factor is exact. Kilocalorie per Kilogram definition: kilocalorie per kilogram; Kilowatt-hour per Kilogram definition: kilowatt-hour per kilogram.
Worked examples
- A reading of 100 kcal/kg converts to 0.1163 kWh/kg.
100 kcal/kg × 0.001163 = 0.1163 kWh/kg - A value of 3500 kcal/kg is 4.0705 kWh/kg.
3500 kcal/kg × 0.001163 = 4.0705 kWh/kg
