About Converting Deciwatts to Nanowatts
Deciwatt and Nanowatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Deciwatt is 0.1 watt units, and nanowatt is 1e-9 watt units.
Formula
nanowatts = deciwatts × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 deciwatt equals 0.1 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct deciwatt-to-nanowatt factor of 100000000.
Simple example
1 dW × 100000000 = 100,000,000 nW
1 deciwatt = 100,000,000 nanowatts.
Real-world example
100 dW × 100000000 = 10,000,000,000 nW
100 deciwatts = 10,000,000,000 nanowatts.

Reverse conversion: Nanowatt to Deciwatt
1 nW × 1e-8 = 1e-8 dW
1 nanowatt = 1e-8 deciwatts.
deciwatts = nanowatts × 1e-8

Frequently asked questions
How many nanowatts are in 1 deciwatt?
1 deciwatt equals 100,000,000 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert deciwatt to nanowatt?
Multiply the deciwatt value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to deciwatt?
Use the reverse factor: 1 nanowatt equals 1e-8 deciwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciwatt?
Deciwatt (dW) is a unit of power.
What is a nanowatt?
Nanowatt (nW) is a unit of power.
Is the deciwatt to nanowatt conversion exact?
Yes. Both deciwatt and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 100000000 used above is exact to as many digits as you choose to display.
