About Converting Microwatts to Nanowatts
Microwatt and Nanowatt 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: Microwatt is 0.000001 watt units, and nanowatt is 1e-9 watt units.
Formula
nanowatts = microwatts × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 microwatt equals 0.000001 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct microwatt-to-nanowatt factor of 1000.
Simple example
1 uW × 1000 = 1,000 nW
1 microwatt = 1,000 nanowatts.
Real-world example
100 uW × 1000 = 100,000 nW
100 microwatts = 100,000 nanowatts.
Conversion table

Reverse conversion: Nanowatt to Microwatt
1 nW × 0.001 = 0.001 uW
1 nanowatt = 0.001 microwatts.
microwatts = nanowatts × 0.001

Frequently asked questions
How many nanowatts are in 1 microwatt?
1 microwatt equals 1,000 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert microwatt to nanowatt?
Multiply the microwatt value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to microwatt?
Use the reverse factor: 1 nanowatt equals 0.001 microwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microwatt?
Microwatt (uW) is a unit of engineering.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
Is the microwatt to nanowatt conversion exact?
Yes. Both microwatt and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
