The Nanowatt Converter supports 24 different power units. This makes it possible to convert freely between nanowatts [nW], metric, Anglo-American, and other power units. All power values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.
Conversion of nanowatts
In order to convert nanowatts [nW] into another unit of measurement, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large, confusing, and difficult for inexperienced users to understand. The tool below provides a solution to this problem by allowing the rounded conversion values for nanowatts [nW] to be queried directly from the conversion table.

Conversion between nanowatts and milliwatts
A quick and precise conversion between nanowatts [nW] and milliwatts [mW] is straightforward and requires only multiplication or division by 1,000,000. The conversion from milliwatts [mW] to nanowatts [nW] is done by multiplying the value in milliwatts [mW] by 1,000,000. To reverse the conversion, divide the value in nanowatts [nW] by 1,000,000 to obtain milliwatts [mW].
- Nanowatts [nW] = milliwatts [mW] * 1,000,000
- Milliwatts [mW] = nanowatts [nW] ÷ 1,000,000
Conversion between nanowatts and watts
Conversions between nanowatts [nW] and watts [W] are straightforward and can be performed with simple math. The required conversion factor is 109. To convert a value from watts [W] to nanowatts [nW], multiply the number of watts [W] by 109. For values in nanowatts [nW], divide by 109 to get the equivalent in watts [W].
- Nanowatts [nW] = watts [W] * 109
- Watts [W] = nanowatts [nW] ÷ 109
Conversion between nanowatts and kilowatts
The conversion between nanowatts [nW] and kilowatts [kW] is quick to perform and requires only basic mathematical operations an the conversion factor 1012. Multiply the number of kilowatts [kW] by 1012 to get the converted value in nanowatts [nW]. To convert a value in nanowatts [nW] back to kilowatts [kW], simply divide the amount of nanowatts [nW] by 1012.
- Nanowatts [nW] = kilowatts [kW] * 1012
- Kilowatts [kW] = nanowatts [nW] ÷ 1012
Conversion between nanowatts and metric horsepower
You can easily convert between metric horsepower [PS] and nanowatts [nW] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Nanowatts [nW] = metric horsepower [PS] * 735.49875 * 109
- Metric horsepower [PS] = nanowatts [nW] ÷ 735.49875 ÷ 109
Conversion between nanowatts and mechanical horsepower
The fastest and easiest way to convert between mechanical horsepower [hp(I)] and nanowatts [nW] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Nanowatts [nW] = mechanical horsepower [hp(I)] * 2,721,554.22 * 273,997.801
- Mechanical horsepower [hp(I)] = nanowatts [nW] ÷ 2,721,554.22 ÷ 273,997.801
