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.
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.
