How to Convert Mechanical Horsepower to Kilocalories Per Hour

To convert a mechanical horsepower measurement to a kilocalorie per hour measurement, multiply the power by the conversion ratio. One mechanical horsepower is equal to 641.615691 kilocalories per hour, so use this simple formula to convert:

kilocalories per hour = mechanical horsepower × 641.615691

The power in kilocalories per hour is equal to the mechanical horsepower multiplied by 641.615691.

For example, here's how to convert 5 mechanical horsepower to kilocalories per hour using the formula above.
5 hp(I) = (5 × 641.615691) = 3,208.078455 kcal/h

Mechanical horsepower and kilocalories per hour are both units used to measure power. Keep reading to learn more about each unit of measure.
