This converter allows you to convert terawatts [TW] to milliwatts [mW] or milliwatts [mW] to terawatts [TW]. 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 terawatt [TW] = 1015 milliwatts [mW]1 milliwatt [mW] = 10-15 terawatts [TW]

Convert terawatts to milliwatts

There are two simple ways to convert terawatts [TW] to milliwatts [mW]. In the first calculation method, the value in terawatts [TW] is divided by 10-15. The second method multiplies the value in terawatts [TW] by 1015.

  • Milliwatts [mW] = terawatts [TW] ÷ 10-15
  • Milliwatts [mW] = terawatts [TW] * 1015

Convert milliwatts to terawatts

Converting milliwatts [mW] to terawatts [TW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliwatts [mW] is multiplied by 10-15. The second variant is a division. Here, the value in milliwatts [mW] is divided by 1015.

  • Terawatts [TW] = milliwatts [mW] * 10-15
  • Terawatts [TW] = milliwatts [mW] ÷ 1015
