This converter allows you to convert terawatts [TW] to nanowatts [nW] or nanowatts [nW] 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] = 1021 nanowatts [nW]1 nanowatt [nW] = 10-21 terawatts [TW]

Convert terawatts to nanowatts

There are two simple ways to convert terawatts [TW] to nanowatts [nW]. In the first calculation method, the value in terawatts [TW] is divided by 10-21. The second method multiplies the value in terawatts [TW] by 1021.

  • Nanowatts [nW] = terawatts [TW] ÷ 10-21
  • Nanowatts [nW] = terawatts [TW] * 1021

Convert nanowatts to terawatts

Converting nanowatts [nW] to terawatts [TW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanowatts [nW] is multiplied by 10-21. The second variant is a division. Here, the value in nanowatts [nW] is divided by 1021.

  • Terawatts [TW] = nanowatts [nW] * 10-21
  • Terawatts [TW] = nanowatts [nW] ÷ 1021
