About Converting Nanowatts to Microwatts
Nanowatt and Microwatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Nanowatt is 1e-9 watt units, and microwatt is 0.000001 watt units.
Formula
microwatts = nanowatts × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 microwatt equals 0.000001 base units, so dividing one by the other gives the direct nanowatt-to-microwatt factor of 0.001.
Simple example
1 nW × 0.001 = 0.001 uW
1 nanowatt = 0.001 microwatts.
Real-world example
100 nW × 0.001 = 0.1 uW
100 nanowatts = 0.1 microwatts.
Conversion table
| Nanowatt (nW) | Microwatt (uW) |
|---|---|
| 1 nW | 0.001 uW |
| 10 nW | 0.01 uW |
| 100 nW | 0.1 uW |
| 500 nW | 0.5 uW |
| 1,000 nW | 1 uW |
| 5,000 nW | 5 uW |
Reverse conversion: Microwatt to Nanowatt
0.001 uW × 1000 = 1 nW
0.001 microwatts = 1 nanowatt.
nanowatts = microwatts × 1000

Frequently asked questions
How many microwatts are in 1 nanowatt?
1 nanowatt equals 0.001 microwatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to microwatt?
Multiply the nanowatt value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert microwatt back to nanowatt?
Use the reverse factor: 1 microwatt equals 1,000 nanowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanowatt?
Nanowatt (nW) is a unit of power.
What is a microwatt?
Microwatt (uW) is a unit of power.
Is the nanowatt to microwatt conversion exact?
Yes. Both nanowatt and microwatt are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
