About Converting Decawatts to Nanowatts
Decawatt and Nanowatt 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: Decawatt is 10 watt units, and nanowatt is 1e-9 watt units.
Formula
nanowatts = decawatts × 10000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 decawatt equals 10 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct decawatt-to-nanowatt factor of 10000000000.
Simple example
1 daW × 10000000000 = 10,000,000,000 nW
1 decawatt = 10,000,000,000 nanowatts.
Real-world example
120 daW × 10000000000 = 1.2e+12 nW
120 decawatts = 1.2e+12 nanowatts.

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

Frequently asked questions
How many nanowatts are in 1 decawatt?
1 decawatt equals 10,000,000,000 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert decawatt to nanowatt?
Multiply the decawatt value by 10000000000. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to decawatt?
Use the reverse factor: 1 nanowatt equals 1e-10 decawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a decawatt?
Decawatt (daW) is a unit of electricity.
What is a nanowatt?
Nanowatt (nW) is a unit of electricity.
Is the decawatt to nanowatt conversion exact?
Yes. Both decawatt and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 10000000000 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.
