About Converting Nanowatts to Microwatts
Nanowatt and Microwatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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 |
| 50 nW | 0.05 uW |
| 100 nW | 0.1 uW |
| 500 nW | 0.5 uW |
| 1,000 nW | 1 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 engineering.
What is a microwatt?
Microwatt (uW) is a unit of engineering.
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.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
