This converter allows you to convert kilocalories per hour [kcal/h] to joules per hour [J/h] or joules per hour [J/h] to kilocalories per hour [kcal/h]. 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 kilocalorie per hour [kcal/h] = 4,186.8 joules per hour [J/h]1 joule per hour [J/h] ≈ 2.388 * 10-4 kilocalories per hour [kcal/h]

Convert kilocalories per hour to joules per hour

There are two simple ways to convert kilocalories per hour [kcal/h] to joules per hour [J/h]. In the first calculation method, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 2.388 * 10-4. The second method multiplies the value in kilocalories per hour [kcal/h] by 4,186.8.

  • Joules per hour [J/h] ≈ kilocalories per hour [kcal/h] ÷ (2.388 * 10-4)
  • Joules per hour [J/h] = kilocalories per hour [kcal/h] * 4,186.8

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


Convert joules per hour to kilocalories per hour

Converting joules per hour [J/h] to kilocalories per hour [kcal/h] is easy and can be done in two ways. The first method involves multiplication, in which the value in joules per hour [J/h] is multiplied by the rounded conversion factor of 2.388 * 10-4. The second variant is a division. Here, the value in joules per hour [J/h] is divided by 4,186.8.

  • Kilocalories per hour [kcal/h] ≈ joules per hour [J/h] * 2.388 * 10-4
  • Kilocalories per hour [kcal/h] = joules per hour [J/h] ÷ 4,186.8

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