Megaelectronvolts to Calories Converter

Convert megaelectronvolts (MeV) to calories (thermochemical) (cal), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

1 MeV = 3.82929405832 × 10⁻¹⁴ cal

Show the working
  1. 1 MeV = 3.82929405832e-14 cal
  2. 1 × 3.82929405832e-14 = 3.82929405832e-14 cal

How to convert megaelectronvolts to calories

1 cal = 26,114,473,967,500 MeV, so divide by 26,114,473,967,500 to go from megaelectronvolts to calories (thermochemical) (1 MeV = 3.82929405832 × 10⁻¹⁴ cal).

cal = MeV ÷ 26,114,473,967,500
MeV = cal × 26,114,473,967,500

Worked example:

1 MeV = 3.82929405832e-14 cal
5 × 3.82929405832e-14 = 1.91464702916e-13 cal

About the units

Megaelectronvolts (MeV)
Megaelectronvolts, a specialised unit. Definition: NIST CODATA: elementary charge (exact since the 2019 SI redefinition).
Calories (cal)
Calories (thermochemical), a specialised unit. The thermochemical calorie, 4.184 J, used on US food labels as 1 Calorie = 1 kilocalorie. Definition: NIST SP 811 Appendix B.8, factors for units listed alphabetically.
