  1. 1 Btu = 0.000293071070172 kWh
  2. 1 × 0.000293071070172 = 0.000293071070172 kWh

How to convert british thermal units to kilowatt-hours

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

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

Worked example:

1 Btu = 0.000293071070172 kWh
5 × 0.000293071070172 = 0.00146535535086 kWh
