How to convert kilocalories to horsepower-hours
hp⋅h = kcal ÷ 641.615568283
To convert kilocalories to horsepower-hours, divide the number of kilocalories by 641.615568283.
Example: 4 kcal to hp⋅h
Start with the value in kilocalories: 4 kcal.
Divide by 641.615568283: 4 ÷ 641.615568283 = 0.006234262692.
Result: 4 kilocalories = 0.006234262692 horsepower-hours .
Going the other way, 1 horsepower-hour = 641.615568283 kilocalories, so to convert horsepower-hours back to kilocalories you multiply by the same number. See horsepower-hours to kilocalories .
