- 1 cal = 1.16222222222e-6 kWh
- 1 × 1.16222222222e-6 = 1.16222222222e-6 kWh
How to convert calories to kilowatt-hours
1 cal = 1.16222222222 × 10⁻⁶ kWh, so multiply by 1.16222222222 to go from calories (thermochemical) to kilowatt-hours. Going the other way, 1 kWh = 860,420.650096 cal.
kWh = cal × 1.16222222222 cal = kWh × 860,420.650096
Worked example:
1 cal = 1.16222222222e-6 kWh 5 × 1.16222222222e-6 = 5.81111111111e-6 kWh
