This converter allows you to convert kilowatts [kW] to kilocalories per hour [kcal/h] or kilocalories per hour [kcal/h] to kilowatts [kW]. 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 kilowatt [kW] ≈ 859.8452 kilocalories per hour [kcal/h]1 kilocalorie per hour [kcal/h] ≈ 0.0012 kilowatts [kW]

Convert kilowatts to kilocalories per hour

There are two simple ways to convert kilowatts [kW] to kilocalories per hour [kcal/h]. In the first calculation method, the value in kilowatts [kW] is divided by the rounded conversion factor of 0.0012. The second method multiplies the value in kilowatts [kW] by the rounded conversion factor of 859.8452.

  • Kilocalories per hour [kcal/h] ≈ kilowatts [kW] ÷ 0.0012
  • Kilocalories per hour [kcal/h] ≈ kilowatts [kW] * 859.8452

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

  • Kilocalories per hour [kcal/h] = kilowatts [kW] * 3,600 ÷ 4.1868

Convert kilocalories per hour to kilowatts

Converting kilocalories per hour [kcal/h] to kilowatts [kW] 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 0.0012. The second variant is a division. Here, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 859.8452.

  • Kilowatts [kW] ≈ kilocalories per hour [kcal/h] * 0.0012
  • Kilowatts [kW] ≈ kilocalories per hour [kcal/h] ÷ 859.8452

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 kilowatts [kW] can be achieved using the following calculation method.

  • Kilowatts [kW] = kilocalories per hour [kcal/h] ÷ 3,600 * 4.1868
