- 1 MeV = 3.82929405832e-17 kcal
- 1 × 3.82929405832e-17 = 3.82929405832e-17 kcal
How to convert megaelectronvolts to kilocalories
1 MeV = 3.82929405832 × 10⁻¹⁷ kcal, so multiply by 3.82929405832 to go from megaelectronvolts to kilocalories (food Calories). Going the other way, 1 kcal = 2.61144739675 × 10¹⁶ MeV.
kcal = MeV × 3.82929405832 MeV = kcal × 2.61144739675
Worked example:
1 MeV = 3.82929405832e-17 kcal 5 × 3.82929405832e-17 = 1.91464702916e-16 kcal
