How to convert kilocalories to watt-hours

Multiply the value in kcal by 1.16222222222: the result is in Wh.

Wh = kcal × 1.16222222222The other way round, 1 Wh = 0.860420650096 kcal.

Where these two units are used

The capital-C Calorie on American labels is a kilocalorie, a thousand physical calories: a bar listed at 200 Calories really holds 200,000 calories in the physicist's sense. The watt-hour measures battery capacity, and it is what airlines read: above 100 watt-hours, a lithium battery boards the cabin only with prior approval. Charging a phone takes about 15 watt-hours, that is 13 kilocalories: less than a mouthful of bread, which gives the measure of the gap between what a body burns and what a device asks for.
