About Converting Nanowatts to Decawatts
Nanowatt and Decawatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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
100 nW × 1e-10 = 1e-8 daW
100 nanowatts = 1e-8 decawatts.
Conversion table
| Nanowatt (nW) | Decawatt (daW) |

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 engineering.
What is a decawatt?
Decawatt (daW) is a unit of engineering.
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.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
