About Converting Centiwatts to Nanowatts
Centiwatt and Nanowatt 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: Centiwatt is 0.01 watt units, and nanowatt is 1e-9 watt units.
Formula
nanowatts = centiwatts × 10000000
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct centiwatt-to-nanowatt factor of 10000000.
Simple example
1 cW × 10000000 = 10,000,000 nW
1 centiwatt = 10,000,000 nanowatts.
Real-world example
100 cW × 10000000 = 1,000,000,000 nW
100 centiwatts = 1,000,000,000 nanowatts.

Reverse conversion: Nanowatt to Centiwatt
1 nW × 1e-7 = 1e-7 cW
1 nanowatt = 1e-7 centiwatts.
centiwatts = nanowatts × 1e-7

Frequently asked questions
How many nanowatts are in 1 centiwatt?
1 centiwatt equals 10,000,000 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert centiwatt to nanowatt?
Multiply the centiwatt value by 10000000. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to centiwatt?
Use the reverse factor: 1 nanowatt equals 1e-7 centiwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a centiwatt?
Centiwatt (cW) is a unit of power.
What is a nanowatt?
Nanowatt (nW) is a unit of power.
Is the centiwatt to nanowatt conversion exact?
Yes. Both centiwatt and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 10000000 used above is exact to as many digits as you choose to display.
