About Converting Nanowatts to Picowatts
Nanowatt and Picowatt 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 picowatt is 1e-12 watt units.
Formula
picowatts = nanowatts × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 picowatt equals 1e-12 base units, so dividing one by the other gives the direct nanowatt-to-picowatt factor of 1000.
Simple example
1 nW × 1000 = 1,000 pW
1 nanowatt = 1,000 picowatts.
Real-world example
100 nW × 1000 = 100,000 pW
100 nanowatts = 100,000 picowatts.
Conversion table
| Nanowatt (nW) | Picowatt (pW) |
|---|---|
| 1 nW | 1,000 pW |
| 10 nW | 10,000 pW |
| 100 nW | 100,000 pW |
| 500 nW | 500,000 pW |
| 1,000 nW | 1,000,000 pW |
| 5,000 nW | 5,000,000 pW |
Reverse conversion: Picowatt to Nanowatt
1 pW × 0.001 = 0.001 nW
1 picowatt = 0.001 nanowatts.
nanowatts = picowatts × 0.001

Frequently asked questions
How many picowatts are in 1 nanowatt?
1 nanowatt equals 1,000 picowatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to picowatt?
Multiply the nanowatt value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert picowatt back to nanowatt?
Use the reverse factor: 1 picowatt equals 0.001 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 picowatt?
Picowatt (pW) is a unit of power.
Is the nanowatt to picowatt conversion exact?
Yes. Both nanowatt and picowatt 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.
