This converter allows you to convert mechanical horsepower [hp(I)] to kilocalories per hour [kcal/h] or kilocalories per hour [kcal/h] to mechanical horsepower [hp(I)]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 mechanical horsepower [hp(I)] ≈ 641.1865 kilocalories per hour [kcal/h]1 kilocalorie per hour [kcal/h] ≈ 0.0016 mechanical horsepower [hp(I)]

Convert mechanical horsepower to kilocalories per hour

There are two simple ways to convert mechanical horsepower [hp(I)] to kilocalories per hour [kcal/h]. In the first calculation method, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 0.0016. The second method multiplies the value in mechanical horsepower [hp(I)] by the rounded conversion factor of 641.1865.

  • Kilocalories per hour [kcal/h] ≈ mechanical horsepower [hp(I)] ÷ 0.0016
  • Kilocalories per hour [kcal/h] ≈ mechanical horsepower [hp(I)] * 641.1865

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of mechanical horsepower [hp(I)] to kilocalories per hour [kcal/h] can be achieved using the following calculation method.

  • Kilocalories per hour [kcal/h] = mechanical horsepower [hp(I)] * 16.32932532 * 164.3986806 ÷ 4.1868

Convert kilocalories per hour to mechanical horsepower

Converting kilocalories per hour [kcal/h] to mechanical horsepower [hp(I)] is easy and can be done in two ways. The first method involves multiplication, in which the value in kilocalories per hour [kcal/h] is multiplied by the rounded conversion factor of 0.0016. The second variant is a division. Here, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 641.1865.

  • Mechanical horsepower [hp(I)] ≈ kilocalories per hour [kcal/h] * 0.0016
  • Mechanical horsepower [hp(I)] ≈ kilocalories per hour [kcal/h] ÷ 641.1865

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of kilocalories per hour [kcal/h] to mechanical horsepower [hp(I)] can be achieved using the following calculation method.

  • Mechanical horsepower [hp(I)] = kilocalories per hour [kcal/h] ÷ 16.32932532 ÷ 164.3986806 * 4.1868
