About Converting Nanowatts to Decawatts
Nanowatt and Decawatt 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 decawatt is 10 watt units.
Formula
decawatts = nanowatts × 1e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct nanowatt-to-decawatt factor of 1e-10.
Simple example
1 nW × 1e-10 = 1e-10 daW
1 nanowatt = 1e-10 decawatts.
Real-world example
120 nW × 1e-10 = 1.2e-8 daW
120 nanowatts = 1.2e-8 decawatts.

Reverse conversion: Decawatt to Nanowatt
1e-10 daW × 10000000000 = 1 nW
1e-10 decawatts = 1 nanowatt.
nanowatts = decawatts × 10000000000

Frequently asked questions
How many decawatts are in 1 nanowatt?
1 nanowatt equals 1e-10 decawatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to decawatt?
Multiply the nanowatt value by 1e-10. The converter above does this instantly to whatever precision you set.
How do I convert decawatt back to nanowatt?
Use the reverse factor: 1 decawatt equals 10,000,000,000 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 decawatt?
Decawatt (daW) is a unit of electricity.
Is the nanowatt to decawatt conversion exact?
Yes. Both nanowatt and decawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-10 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.
