Megaelectronvolts to Therms Converter

Convert megaelectronvolts (MeV) to therms (100,000 Btu) (thm), 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.

How to convert megaelectronvolts to therms

1 MeV = 1.51857044347 × 10⁻²¹ thm, so multiply by 1.51857044347 to go from megaelectronvolts to therms (100,000 Btu). Going the other way, 1 thm = 6.58514067819 × 10²⁰ MeV.

thm = MeV × 1.51857044347
MeV = thm × 6.58514067819

Worked example:

1 MeV = 1.51857044347e-21 thm
5 × 1.51857044347e-21 = 7.59285221736e-21 thm

About the units

Megaelectronvolts (MeV)
Megaelectronvolts, a specialised unit. Definition: NIST CODATA: elementary charge (exact since the 2019 SI redefinition).
Therms (thm)
Therms (100,000 Btu), a US customary unit. The EC/IT therm; the US therm is 105,480,400 J, 0.02% smaller. Definition: NIST SP 811 Appendix B.8, factors for units listed alphabetically.
