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
