This converter allows you to convert joules per hour [J/h] to nanowatts [nW] or nanowatts [nW] to joules per hour [J/h]. 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 hour [J/h] ≈ 277,777.7778 nanowatts [nW]1 nanowatt [nW] = 3.6 * 10-6 joules per hour [J/h]

Convert joules per hour to nanowatts

There are two simple ways to convert joules per hour [J/h] to nanowatts [nW]. In the first calculation method, the value in joules per hour [J/h] is divided by 3.6 * 10-6. The second method multiplies the value in joules per hour [J/h] by the rounded conversion factor of 277,777.7778.

  • Nanowatts [nW] = joules per hour [J/h] ÷ (3.6 * 10-6)
  • Nanowatts [nW] ≈ joules per hour [J/h] * 277,777.7778

However, the calculation method with rounded conversion values is only suitable for rough conversions from joules per hour [J/h] to nanowatts [nW], as rounding errors may occur in the calculation results. The following formula shows another variant that can be used to calculate results as accurately as possible.

  • Nanowatts [nW] = joules per hour [J/h] ÷ 3.6 * 106

Convert nanowatts to joules per hour

Converting nanowatts [nW] to joules per hour [J/h] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanowatts [nW] is multiplied by 3.6 * 10-6. The second variant is a division. Here, the value in nanowatts [nW] is divided by the rounded conversion factor of 277,777.7778.

  • Joules per hour [J/h] = nanowatts [nW] * 3.6 * 10-6
  • Joules per hour [J/h] ≈ nanowatts [nW] ÷ 277,777.7778

However, the version with rounded conversion values can produce somewhat inaccurate calculation results, which is why it is only suitable for rough conversions from nanowatts [nW] to joules per hour [J/h]. The formula below shows an alternative method that can be used to calculate results as accurately as possible.

  • Joules per hour [J/h] = nanowatts [nW] * 3.6 ÷ 106
