This converter allows you to convert kilowatts [kW] to milliwatts [mW] or milliwatts [mW] to kilowatts [kW]. 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 kilowatt [kW] = 1,000,000 milliwatts [mW]1 milliwatt [mW] = 10-6 kilowatts [kW]

Convert kilowatts to milliwatts

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

  • Milliwatts [mW] = kilowatts [kW] ÷ 10-6
  • Milliwatts [mW] = kilowatts [kW] * 1,000,000

Convert milliwatts to kilowatts

Converting milliwatts [mW] to kilowatts [kW] 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.

  • Kilowatts [kW] = milliwatts [mW] * 10-6
  • Kilowatts [kW] = 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.
