This converter allows you to convert kilojoules per second [kJ/s] to kilojoules per hour [kJ/h] or kilojoules per hour [kJ/h] to kilojoules per second [kJ/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 kilojoule per second [kJ/s] = 3,600 kilojoules per hour [kJ/h]1 kilojoule per hour [kJ/h] ≈ 2.778 * 10-4 kilojoules per second [kJ/s]

Convert kilojoules per second to kilojoules per hour

There are two simple ways to convert kilojoules per second [kJ/s] to kilojoules per hour [kJ/h]. In the first calculation method, the value in kilojoules per second [kJ/s] is divided by the rounded conversion factor of 2.778 * 10-4. The second method multiplies the value in kilojoules per second [kJ/s] by 3,600.

  • Kilojoules per hour [kJ/h] ≈ kilojoules per second [kJ/s] ÷ (2.778 * 10-4)
  • Kilojoules per hour [kJ/h] = kilojoules per second [kJ/s] * 3,600

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


Convert kilojoules per hour to kilojoules per second

Converting kilojoules per hour [kJ/h] to kilojoules per second [kJ/s] is easy and can be done in two ways. The first method involves multiplication, in which the value in kilojoules per hour [kJ/h] is multiplied by the rounded conversion factor of 2.778 * 10-4. The second variant is a division. Here, the value in kilojoules per hour [kJ/h] is divided by 3,600.

  • Kilojoules per second [kJ/s] ≈ kilojoules per hour [kJ/h] * 2.778 * 10-4
  • Kilojoules per second [kJ/s] = kilojoules per hour [kJ/h] ÷ 3,600

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