  1. 1 Mcal = 1000 kcal
  2. 1 × 1000 = 1000 kcal

How to convert megacalories to kilocalories

1 Mcal = 1,000 kcal, so multiply by 1,000 to go from megacalories to kilocalories (food Calories). Going the other way, 1 kcal = 0.001 Mcal.

kcal = Mcal × 1,000
Mcal = kcal × 0.001

Worked example:

1 Mcal = 1000 kcal
5 × 1000 = 5000 kcal
