The Kilojoule per second Converter supports 24 different power units. This makes it possible to convert freely between kilojoules per second [kJ/s], metric, Anglo-American, and other power units. All power values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.


Conversion of kilojoules per second

In order to convert kilojoules per second [kJ/s] into another unit of measurement, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large, confusing, and difficult for inexperienced users to understand. The tool below provides a solution to this problem by allowing the rounded conversion values for kilojoules per second [kJ/s] to be queried directly from the conversion table.

Conversion between kilojoules per second and milliwatts

A quick and precise conversion between kilojoules per second [kJ/s] and milliwatts [mW] is straightforward and requires only multiplication or division by 1,000,000. The conversion from kilojoules per second [kJ/s] to milliwatts [mW] is done by multiplying the value in kilojoules per second [kJ/s] by 1,000,000. To reverse the conversion, divide the value in milliwatts [mW] by 1,000,000 to obtain kilojoules per second [kJ/s].

  • Milliwatts [mW] = kilojoules per second [kJ/s] * 1,000,000
  • Kilojoules per second [kJ/s] = milliwatts [mW] ÷ 1,000,000

Conversion between kilojoules per second and watts

Conversions between kilojoules per second [kJ/s] and watts [W] are straightforward and can be performed with simple math. The required conversion factor is 1,000. To convert a value from kilojoules per second [kJ/s] to watts [W], multiply the number of kilojoules per second [kJ/s] by 1,000. For values in watts [W], divide by 1,000 to get the equivalent in kilojoules per second [kJ/s].

  • Watts [W] = kilojoules per second [kJ/s] * 1,000
  • Kilojoules per second [kJ/s] = watts [W] ÷ 1,000

Conversion between kilojoules per second and metric horsepower

You can easily convert between metric horsepower [PS] and kilojoules per second [kJ/s] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.

  • Kilojoules per second [kJ/s] = metric horsepower [PS] * 0.73549875
  • Metric horsepower [PS] = kilojoules per second [kJ/s] ÷ 0.73549875

Conversion between kilojoules per second and mechanical horsepower

The fastest and easiest way to convert between mechanical horsepower [hp(I)] and kilojoules per second [kJ/s] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.

  • Kilojoules per second [kJ/s] = mechanical horsepower [hp(I)] * 0.272155422 * 2.73997801
  • Mechanical horsepower [hp(I)] = kilojoules per second [kJ/s] ÷ 0.272155422 ÷ 2.73997801

Conversion between kilojoules per second and kilojoules per minute

The conversion between kilojoules per second [kJ/s] and kilojoules per minute [kJ/min] is quick to perform and requires only basic mathematical operations an the conversion factor 60. Multiply the number of kilojoules per second [kJ/s] by 60 to get the converted value in kilojoules per minute [kJ/min]. To convert a value in kilojoules per minute [kJ/min] back to kilojoules per second [kJ/s], simply divide the amount of kilojoules per minute [kJ/min] by 60.

  • Kilojoules per minute [kJ/min] = kilojoules per second [kJ/s] * 60
  • Kilojoules per second [kJ/s] = kilojoules per minute [kJ/min] ÷ 60
