About Converting Deciwatts to Hectowatts
Deciwatt and Hectowatt 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 hectowatt is 100 watt units.
Formula
hectowatts = deciwatts × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 deciwatt equals 0.1 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct deciwatt-to-hectowatt factor of 0.001.
Simple example
1 dW × 0.001 = 0.001 hW
1 deciwatt = 0.001 hectowatts.
Real-world example
100 dW × 0.001 = 0.1 hW
100 deciwatts = 0.1 hectowatts.
Conversion table
| Deciwatt (dW) | Hectowatt (hW) |

Reverse conversion: Hectowatt to Deciwatt
0.001 hW × 1000 = 1 dW
0.001 hectowatts = 1 deciwatt.
deciwatts = hectowatts × 1000

Frequently asked questions
How many hectowatts are in 1 deciwatt?
1 deciwatt equals 0.001 hectowatts, using the exact defined conversion factor rather than an estimate.
How do I convert deciwatt to hectowatt?
Multiply the deciwatt value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert hectowatt back to deciwatt?
Use the reverse factor: 1 hectowatt equals 1,000 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 hectowatt?
Hectowatt (hW) is a unit of power.
Is the deciwatt to hectowatt conversion exact?
Yes. Both deciwatt and hectowatt are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
