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?

Yes. In nutrition, a "Calorie" (capital C) equals one kilocalorie. So 860 Cal/h = 860 kcal/h = about 1,000 W.

How many watts are in 1 kilocalories/hour?

1 kcal/h equals 1.163 W.

How do you convert kilocalories/hour to watts?

Multiply the kilocalories/hour value by 1.163. Formula: W = kcal/h × 1.163.

How many watts are in 5 kilocalories/hour?

5 kcal/h = 5.815 W.

How do you convert watts back to kilocalories/hour?

Use the inverse formula: kcal/h = W ÷ 1.163. For example, 1 W = 0.859845 kcal/h.

What is the difference between Kilocalories/hour and Watt?

One kilocalorie per hour equals approximately 1.163 watts. The watt is the SI derived unit of power, equal to one joule per second (1 W = 1 J/s = 1 V·A).
