1 MMBtu = 252,164.400722 kcal

Show the working
  1. 1 MMBtu = 252164.400722 kcal
  2. 1 × 252164.400722 = 252164.400722 kcal

How to convert million btu to kilocalories

1 MMBtu = 252,164.400722 kcal, so multiply by 252,164.400722 to go from million Btu to kilocalories (food Calories). Going the other way, 1 kcal = 3.96566683139 × 10⁻⁶ MMBtu.

kcal = MMBtu × 252,164.400722
MMBtu = kcal × 3.96566683139

Worked example:

1 MMBtu = 252164.400722 kcal
5 × 252164.400722 = 1260822.00361 kcal
