Show the working
  1. 1 mW = 0.000860420650096 kcal/h
  2. 1 × 0.000860420650096 = 0.000860420650096 kcal/h

How to convert milliwatts to kilocalories per hour

1 mW = 0.000860420650096 kcal/h, so multiply by 0.000860420650096 to go from milliwatts to kilocalories per hour. Going the other way, 1 kcal/h = 1,162.22222222 mW.

kcal/h = mW × 0.000860420650096
mW = kcal/h × 1,162.22222222

Worked example:

1 mW = 0.000860420650096 kcal/h
5 × 0.000860420650096 = 0.00430210325048 kcal/h
