Show the working
  1. 1 keV = 1.51857044347e-25 MMBtu
  2. 1 × 1.51857044347e-25 = 1.51857044347e-25 MMBtu

How to convert kiloelectronvolts to million btu

1 keV = 1.51857044347 × 10⁻²⁵ MMBtu, so multiply by 1.51857044347 to go from kiloelectronvolts to million Btu. Going the other way, 1 MMBtu = 6.58514067819 × 10²⁴ keV.

MMBtu = keV × 1.51857044347
keV = MMBtu × 6.58514067819

Worked example:

1 keV = 1.51857044347e-25 MMBtu
5 × 1.51857044347e-25 = 7.59285221736e-25 MMBtu
