About Converting Nanowatts to Centiwatts
Nanowatt and Centiwatt 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: 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
120 nW × 1e-7 = 0.000012 cW
120 nanowatts = 0.000012 centiwatts.

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 electricity.
What is a centiwatt?
Centiwatt (cW) is a unit of electricity.
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.
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.
