Calories to Megaelectronvolts Converter

Convert calories (thermochemical) (cal) to megaelectronvolts (MeV), 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 cal = 26,114,473,967,500 MeV

Show the working
  1. 1 cal = 26114473967500 MeV
  2. 1 × 26114473967500 = 26114473967500 MeV

How to convert calories to megaelectronvolts

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

MeV = cal × 26,114,473,967,500
cal = MeV × 3.82929405832

Worked example:

1 cal = 26114473967500 MeV
5 × 26114473967500 = 130572369838000 MeV

About the units

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.
Megaelectronvolts (MeV)
Megaelectronvolts, a specialised unit. Definition: NIST CODATA: elementary charge (exact since the 2019 SI redefinition).
