How to Convert Kilowatt-hour per Kilogram to Calorie per Gram
- 1 kWh/kg = 859.8452279 cal/g
- 1 cal/g = 0.001163 kWh/kg
- Example: convert 15 kWh/kg to cal/g: 15 kWh/kg = 15 × 859.8452279 cal/g = 12897.67842 cal/g
Reference conditions. cal/g: International Table calorie (4.1868 J).
Formula
cal/g = kWh/kg × 859.845227859
Derivation from SI units:
- 1 kWh/kg = 3.6 × 10⁶ J/kg.
- 1 cal_IT/g = 4186.8 J/kg = 1 kcal/kg.
- 1 kWh/kg = 3600000 J/kg ÷ 4186.8 J/kg per cal/g = 859.845227859 cal/g
Both units are defined exactly, so the factor is exact. Kilowatt-hour per Kilogram definition: kilowatt-hour per kilogram; Calorie per Gram definition: calorie per gram.
Worked examples
- A reading of 1 kWh/kg converts to 859.8452279 cal/g.
1 kWh/kg × 859.8452279 = 859.8452279 cal/g - A value of 12 kWh/kg is 10318.14273 cal/g.
12 kWh/kg × 859.8452279 = 10318.14273 cal/g
