Context values
Some unit families need one extra value for a physically accurate result.
Nanowatt is 1e-9 watt units.
Result = input x 1e-6 / 1e-9.

About Converting Microwatts to Nanowatts
Microwatt and Nanowatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. 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
120 uW × 1000 = 120,000 nW
120 microwatts = 120,000 nanowatts.

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 electricity.
What is a nanowatt?
Nanowatt (nW) is a unit of electricity.
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.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
