About Converting Nanowatts to Centiwatts
Nanowatt and Centiwatt 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 centiwatt is 0.01 watt units.
Formula
centiwatts = nanowatts × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 centiwatt equals 0.01 base units, so dividing one by the other gives the direct nanowatt-to-centiwatt factor of 1e-7.
Simple example
1 nW × 1e-7 = 1e-7 cW
1 nanowatt = 1e-7 centiwatts.
Real-world example
100 nW × 1e-7 = 0.00001 cW
100 nanowatts = 0.00001 centiwatts.
Conversion table
| Nanowatt (nW) | Centiwatt (cW) |
|---|---|
| 1 nW | 1e-7 cW |
| 10 nW | 0.000001 cW |
| 100 nW | 0.00001 cW |
| 500 nW | 0.00005 cW |
| 1,000 nW | 0.0001 cW |
| 5,000 nW | 0.0005 cW |
Reverse conversion: Centiwatt to Nanowatt
1e-7 cW × 10000000 = 1 nW
1e-7 centiwatts = 1 nanowatt.
nanowatts = centiwatts × 10000000

Frequently asked questions
How many centiwatts are in 1 nanowatt?
1 nanowatt equals 1e-7 centiwatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to centiwatt?
Multiply the nanowatt value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert centiwatt back to nanowatt?
Use the reverse factor: 1 centiwatt equals 10,000,000 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 centiwatt?
Centiwatt (cW) is a unit of power.
Is the nanowatt to centiwatt conversion exact?
Yes. Both nanowatt and centiwatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 used above is exact to as many digits as you choose to display.
