Megaelectronvolts to British Thermal Units Converter

Convert megaelectronvolts (MeV) to British thermal units (IT) (Btu), 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 british thermal units

1 MeV = 1.51857044347 × 10⁻¹⁶ Btu, so multiply by 1.51857044347 to go from megaelectronvolts to British thermal units (IT). Going the other way, 1 Btu = 6.58514067819 × 10¹⁵ MeV.

Btu = MeV × 1.51857044347
MeV = Btu × 6.58514067819

Worked example:

1 MeV = 1.51857044347e-16 Btu
5 × 1.51857044347e-16 = 7.59285221736e-16 Btu
