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

Convert kilocalories per second to joules per second

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

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

The calculation method with a rounded conversion value is more suitable for rough conversions from kilocalories per second [kcal/s] 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 second

Converting joules per second [J/s] to kilocalories per second [kcal/s] 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 2.388 * 10-4. The second variant is a division. Here, the value in joules per second [J/s] is divided by 4,186.8.

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

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 second [kcal/s] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
