This converter allows you to convert joules per second [J/s] to nanowatts [nW] or nanowatts [nW] to joules per second [J/s]. 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 joule per second [J/s] = 109 nanowatts [nW]1 nanowatt [nW] = 10-9 joules per second [J/s]

Convert joules per second to nanowatts

There are two simple ways to convert joules per second [J/s] to nanowatts [nW]. In the first calculation method, the value in joules per second [J/s] is divided by 10-9. The second method multiplies the value in joules per second [J/s] by 109.

  • Nanowatts [nW] = joules per second [J/s] ÷ 10-9
  • Nanowatts [nW] = joules per second [J/s] * 109

Convert nanowatts to joules per second

Converting nanowatts [nW] to joules per second [J/s] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanowatts [nW] is multiplied by 10-9. The second variant is a division. Here, the value in nanowatts [nW] is divided by 109.

  • Joules per second [J/s] = nanowatts [nW] * 10-9
  • Joules per second [J/s] = nanowatts [nW] ÷ 109
