  1. 1 kWh = 860420.650096 cal
  2. 1 × 860420.650096 = 860420.650096 cal

How to convert kilowatt-hours to calories

1 kWh = 860,420.650096 cal, so multiply by 860,420.650096 to go from kilowatt-hours to calories (thermochemical). Going the other way, 1 cal = 1.16222222222 × 10⁻⁶ kWh.

cal = kWh × 860,420.650096
kWh = cal × 1.16222222222

Worked example:

1 kWh = 860420.650096 cal
5 × 860420.650096 = 4302103.25048 cal
