This converter allows you to convert watts [W] to kilocalories per hour [kcal/h] or kilocalories per hour [kcal/h] to watts [W]. 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 watt [W] ≈ 0.8598 kilocalories per hour [kcal/h]1 kilocalorie per hour [kcal/h] = 1.163 watts [W]

Convert watts to kilocalories per hour

There are two simple ways to convert watts [W] to kilocalories per hour [kcal/h]. In the first calculation method, the value in watts [W] is divided by 1.163. The second method multiplies the value in watts [W] by the rounded conversion factor of 0.8598.

  • Kilocalories per hour [kcal/h] = watts [W] ÷ 1.163
  • Kilocalories per hour [kcal/h] ≈ watts [W] * 0.8598

The calculation method with a rounded conversion value is more suitable for rough conversions from watts [W] to kilocalories per hour [kcal/h], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert kilocalories per hour to watts

Converting kilocalories per hour [kcal/h] to watts [W] is easy and can be done in two ways. The first method involves multiplication, whereby the value in kilocalories per hour [kcal/h] is multiplied by 1.163. The second variant is a division. Here, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 0.8598.

  • Watts [W] = kilocalories per hour [kcal/h] * 1.163
  • Watts [W] ≈ kilocalories per hour [kcal/h] ÷ 0.8598

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from kilocalories per hour [kcal/h] to watts [W] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
