This converter allows you to convert hectowatts [hW] to milliwatts [mW] or milliwatts [mW] to hectowatts [hW]. 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 hectowatt [hW] = 100,000 milliwatts [mW]1 milliwatt [mW] = 10-5 hectowatts [hW]

Convert hectowatts to milliwatts

There are two simple ways to convert hectowatts [hW] to milliwatts [mW]. In the first calculation method, the value in hectowatts [hW] is divided by 10-5. The second method multiplies the value in hectowatts [hW] by 100,000.

  • Milliwatts [mW] = hectowatts [hW] ÷ 10-5
  • Milliwatts [mW] = hectowatts [hW] * 100,000

Convert milliwatts to hectowatts

Converting milliwatts [mW] to hectowatts [hW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliwatts [mW] is multiplied by 10-5. The second variant is a division. Here, the value in milliwatts [mW] is divided by 100,000.

  • Hectowatts [hW] = milliwatts [mW] * 10-5
  • Hectowatts [hW] = milliwatts [mW] ÷ 100,000
