About Converting Deciwatts to Kilowatts
Deciwatt and Kilowatt 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 kilowatt is 1000 watt units.
Formula
kilowatts = deciwatts × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 deciwatt equals 0.1 base units, and 1 kilowatt equals 1000 base units, so dividing one by the other gives the direct deciwatt-to-kilowatt factor of 0.0001.
Simple example
1 dW × 0.0001 = 0.0001 kW
1 deciwatt = 0.0001 kilowatts.
Real-world example
100 dW × 0.0001 = 0.01 kW
100 deciwatts = 0.01 kilowatts.
Conversion table
| Deciwatt (dW) | Kilowatt (kW) |
|---|---|
| 1 dW | 0.0001 kW |
| 10 dW | 0.001 kW |
| 100 dW | 0.01 kW |
| 500 dW | 0.05 kW |
| 1,000 dW | 0.1 kW |
| 5,000 dW | 0.5 kW |
Reverse conversion: Kilowatt to Deciwatt
0.0001 kW × 10000 = 1 dW
0.0001 kilowatts = 1 deciwatt.
deciwatts = kilowatts × 10000

Understanding the Deciwatt (dW)
Deciwatt is 0.1 watt units.
Understanding the Kilowatt
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard power unit worldwide for larger appliances, vehicles, and electrical systems
Uses of the Kilowatt today
- Electric vehicle motor power ratings (alongside horsepower)
- Household electrical system and generator capacity
- Industrial motor and equipment power ratings
History of the Kilowatt
The kilowatt follows directly from the watt via the standard SI 'kilo-' prefix, becoming especially prominent with the growth of electrical power generation and distribution in the late 19th and 20th centuries.
Historical origin. Kilowatt was not the invention of a single named person; it developed through the process described above.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

Frequently asked questions
How many kilowatts are in 1 deciwatt?
1 deciwatt equals 0.0001 kilowatts, using the exact defined conversion factor rather than an estimate.
How do I convert deciwatt to kilowatt?
Multiply the deciwatt value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert kilowatt back to deciwatt?
Use the reverse factor: 1 kilowatt equals 10,000 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 kilowatt?
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Is the deciwatt to kilowatt conversion exact?
Yes. Both deciwatt and kilowatt are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 used above is exact to as many digits as you choose to display.
