FAQ

What is the conversion factor from kcal/lb to kcal/kg?
1 kcal/lb equals 2.204623 kcal/kg. To convert, multiply the value in kilocalories per pound by 2.204623.
How do I convert 1 kcal/lb to kcal/kg?
1 kcal/lb = 2.20462 kcal/kg. For any value, multiply by 2.204623.
How do I convert kcal/kg back to kcal/lb?
