This converter allows you to convert kilojoules per second [kJ/s] to milliwatts [mW] or milliwatts [mW] 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] = 1,000,000 milliwatts [mW]1 milliwatt [mW] = 10-6 kilojoules per second [kJ/s]

Convert kilojoules per second to milliwatts

There are two simple ways to convert kilojoules per second [kJ/s] to milliwatts [mW]. In the first calculation method, the value in kilojoules per second [kJ/s] is divided by 10-6. The second method multiplies the value in kilojoules per second [kJ/s] by 1,000,000.

  • Milliwatts [mW] = kilojoules per second [kJ/s] ÷ 10-6
  • Milliwatts [mW] = kilojoules per second [kJ/s] * 1,000,000

Convert milliwatts to kilojoules per second

Converting milliwatts [mW] to kilojoules per second [kJ/s] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliwatts [mW] is multiplied by 10-6. The second variant is a division. Here, the value in milliwatts [mW] is divided by 1,000,000.

  • Kilojoules per second [kJ/s] = milliwatts [mW] * 10-6
  • Kilojoules per second [kJ/s] = milliwatts [mW] ÷ 1,000,000

Resistance

Electrical resistance is often expressed in ohms or kiloohms. However, it is also possible to use statohms or deciohms. The resistance converter is ideal for converting between different units of resistance.

Speed

While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
