British Thermal Units to Megaelectronvolts Converter

Convert British thermal units (IT) (Btu) 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.

How to convert british thermal units to megaelectronvolts

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

MeV = Btu × 6.58514067819
Btu = MeV × 1.51857044347

Worked example:

1 Btu = 6.58514067819e15 MeV
5 × 6.58514067819e15 = 3.2925703391e16 MeV
