1 kcal = 0.00116222222222 kWh

Show the working
  1. 1 kcal = 0.00116222222222 kWh
  2. 1 × 0.00116222222222 = 0.00116222222222 kWh

How to convert kilocalories to kilowatt-hours

1 kcal = 0.00116222222222 kWh, so multiply by 0.00116222222222 to go from kilocalories (food Calories) to kilowatt-hours. Going the other way, 1 kWh = 860.420650096 kcal.

kWh = kcal × 0.00116222222222
kcal = kWh × 860.420650096

Worked example:

1 kcal = 0.00116222222222 kWh
5 × 0.00116222222222 = 0.00581111111111 kWh
