How to convert kilowatt-hours to megacalories

1 kWh = 0.860420650096 Mcal, so multiply by 0.860420650096 to go from kilowatt-hours to megacalories. Going the other way, 1 Mcal = 1.16222222222 kWh.

Mcal = kWh × 0.860420650096
kWh = Mcal × 1.16222222222

Worked example:

1 kWh = 0.860420650096 Mcal
5 × 0.860420650096 = 4.30210325048 Mcal
