How to convert kilowatt-hours to british thermal units

1 kWh = 3,412.14163313 Btu, so multiply by 3,412.14163313 to go from kilowatt-hours to British thermal units (IT). Going the other way, 1 Btu = 0.000293071070172 kWh.

Btu = kWh × 3,412.14163313
kWh = Btu × 0.000293071070172

Worked example:

1 kWh = 3412.14163313 Btu
5 × 3412.14163313 = 17060.7081656 Btu
