- 1 W = 0.860420650096 kcal/h
- 1 × 0.860420650096 = 0.860420650096 kcal/h
How to convert watts to kilocalories per hour
1 W = 0.860420650096 kcal/h, so multiply by 0.860420650096 to go from watts to kilocalories per hour. Going the other way, 1 kcal/h = 1.16222222222 W.
kcal/h = W × 0.860420650096 W = kcal/h × 1.16222222222
Worked example:
1 W = 0.860420650096 kcal/h 5 × 0.860420650096 = 4.30210325048 kcal/h
