Kilowatt-hours to Kilocalories (kWh to kcal) Converter
1 kilowatt-hour equals 860.42065 kilocalories (kcal) — multiply kilowatt-hours by 860.42065 to convert. This factor comes from the fact that 1 kWh is 3,600,000 joules and 1 kcal is 4,184 joules, so 3,600,000 ÷ 4,184 = 860.42065 kcal.
The formula
To convert kilowatt-hours to kilocalories, multiply by the exact factor:
kcal = kWh × 860.42065
