About Converting Decawatts to Nanowatts
Decawatt and Nanowatt 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: 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
100 daW × 10000000000 = 1,000,000,000,000 nW
100 decawatts = 1,000,000,000,000 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 engineering.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
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.
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.
