About Converting Nanowatts to Deciwatts
Nanowatt and Deciwatt 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: Nanowatt is 1e-9 watt units, and deciwatt is 0.1 watt units.
Formula
deciwatts = nanowatts × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 deciwatt equals 0.1 base units, so dividing one by the other gives the direct nanowatt-to-deciwatt factor of 1e-8.
Simple example
1 nW × 1e-8 = 1e-8 dW
1 nanowatt = 1e-8 deciwatts.
Real-world example
100 nW × 1e-8 = 0.000001 dW
100 nanowatts = 0.000001 deciwatts.
Conversion table
| Nanowatt (nW) | Deciwatt (dW) |
|---|---|
| 1 nW | 1e-8 dW |
| 10 nW | 1e-7 dW |
| 100 nW | 0.000001 dW |
| 500 nW | 0.000005 dW |
| 1,000 nW | 0.00001 dW |
| 5,000 nW | 0.00005 dW |
Reverse conversion: Deciwatt to Nanowatt
1e-8 dW × 100000000 = 1 nW
1e-8 deciwatts = 1 nanowatt.
nanowatts = deciwatts × 100000000

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