How to Convert Kilocalorie per Kilogram to Calorie per Gram
- 1 kcal/kg = 1 cal/g
- 1 cal/g = 1 kcal/kg
- Example: convert 15 kcal/kg to cal/g: 15 kcal/kg = 15 × 1 cal/g = 15 cal/g
Reference conditions. kcal/kg: International Table calorie (4.1868 J). cal/g: International Table calorie (4.1868 J).
Formula
cal/g = kcal/kg × 1
Derivation from SI units:
- 1 kcal_IT/kg = 4186.8 J/kg.
- 1 cal_IT/g = 4186.8 J/kg = 1 kcal/kg.
- 1 kcal/kg = 4186.8 J/kg ÷ 4186.8 J/kg per cal/g = 1 cal/g
Both units are defined exactly, so the factor is exact. Kilocalorie per Kilogram definition: kilocalorie per kilogram; Calorie per Gram definition: calorie per gram.
Worked examples
- A reading of 100 kcal/kg converts to 100 cal/g.
100 kcal/kg × 1 = 100 cal/g - A value of 3500 kcal/kg is 3500 cal/g.
3500 kcal/kg × 1 = 3500 cal/g

Where it's used
Kilocalories per Kilogram are used for indian coal grading (GCV in kcal/kg), while calories per gram appear in latent heat problems in CGS units. Both measure specific energy: enthalpy, latent heat and heating value per mass, so the conversion is a fixed factor.
