This converter allows you to convert kilocalories per hour [kcal/h] to joules per second [J/s] or joules per second [J/s] 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] = 1.163 joules per second [J/s]1 joule per second [J/s] ≈ 0.8598 kilocalories per hour [kcal/h]

Convert kilocalories per hour to joules per second

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

  • Joules per second [J/s] ≈ kilocalories per hour [kcal/h] ÷ 0.8598
  • Joules per second [J/s] = kilocalories per hour [kcal/h] * 1.163

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


Convert joules per second to kilocalories per hour

Converting joules per second [J/s] 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 second [J/s] is multiplied by the rounded conversion factor of 0.8598. The second variant is a division. Here, the value in joules per second [J/s] is divided by 1.163.

  • Kilocalories per hour [kcal/h] ≈ joules per second [J/s] * 0.8598
  • Kilocalories per hour [kcal/h] = joules per second [J/s] ÷ 1.163

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