FAQ

How do I convert kilocalories per hour to watts?

Multiply the kcal/h value by 1.163. For example, 860 kcal/h = 1,000.18 W (approximately 1 kW).

Where is kcal/h used as a power unit?

Kilocalories per hour appear in HVAC specifications, metabolic rate calculations, and some European heating equipment ratings.

What is the human body metabolic rate in kcal/h?

A resting adult generates about 60-80 kcal/h (70-93 W). During exercise, this can increase to 500-1,000 kcal/h or more.

Is kcal/h the same as Calories per hour?
