This converter allows you to convert megawatts [MW] to milliwatts [mW] or milliwatts [mW] to megawatts [MW]. 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 megawatt [MW] = 109 milliwatts [mW]1 milliwatt [mW] = 10-9 megawatts [MW]

Convert megawatts to milliwatts

There are two simple ways to convert megawatts [MW] to milliwatts [mW]. In the first calculation method, the value in megawatts [MW] is divided by 10-9. The second method multiplies the value in megawatts [MW] by 109.

  • Milliwatts [mW] = megawatts [MW] ÷ 10-9
  • Milliwatts [mW] = megawatts [MW] * 109

Convert milliwatts to megawatts

Converting milliwatts [mW] to megawatts [MW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliwatts [mW] is multiplied by 10-9. The second variant is a division. Here, the value in milliwatts [mW] is divided by 109.

  • Megawatts [MW] = milliwatts [mW] * 10-9
  • Megawatts [MW] = milliwatts [mW] ÷ 109
