This converter allows you to convert kilojoules per second [kJ/s] to joules per second [J/s] or joules per second [J/s] 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] = 1,000 joules per second [J/s]1 joule per second [J/s] = 0.001 kilojoules per second [kJ/s]

Convert kilojoules per second to joules per second

There are two simple ways to convert kilojoules per second [kJ/s] to joules per second [J/s]. In the first calculation method, the value in kilojoules per second [kJ/s] is divided by 0.001. The second method multiplies the value in kilojoules per second [kJ/s] by 1,000.

  • Joules per second [J/s] = kilojoules per second [kJ/s] ÷ 0.001
  • Joules per second [J/s] = kilojoules per second [kJ/s] * 1,000

Convert joules per second to kilojoules per second

Converting joules per second [J/s] to kilojoules per second [kJ/s] is easy and can be done in two ways. The first method involves multiplication, whereby the value in joules per second [J/s] is multiplied by 0.001. The second variant is a division. Here, the value in joules per second [J/s] is divided by 1,000.

  • Kilojoules per second [kJ/s] = joules per second [J/s] * 0.001
  • Kilojoules per second [kJ/s] = joules per second [J/s] ÷ 1,000
