Kilowatt is 1000 watt units.
Kilowatts to Deciwatts Converter — kW to dW
Convert Kilowatt (kW) to Deciwatt (dW) using the exact conversion factor (1 kilowatt = 10,000 deciwatt). See the formula, worked examples, conversion table, history, and common uses.

Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Deciwatt is 0.1 watt units.
Result = input x 1000 / 0.1.

About Converting Kilowatts to Deciwatts
Kilowatt and Deciwatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Kilowatt is most often used for electric vehicle motor power ratings (alongside horsepower).
Formula
deciwatts = kilowatts × 10000
This factor comes from each unit's defined relationship to the category's base unit: 1 kilowatt equals 1000 base units, and 1 deciwatt equals 0.1 base units, so dividing one by the other gives the direct kilowatt-to-deciwatt factor of 10000.
Simple example
1 kW × 10000 = 10,000 dW
1 kilowatt = 10,000 deciwatts.
Real-world example
120 kW × 10000 = 1,200,000 dW
120 kilowatts = 1,200,000 deciwatts.
Conversion table
| Kilowatt (kW) | Deciwatt (dW) |
|---|---|
| 1 kW | 10,000 dW |
| 5 kW | 50,000 dW |
| 12 kW | 120,000 dW |
| 24 kW | 240,000 dW |
| 120 kW | 1,200,000 dW |
| 240 kW | 2,400,000 dW |
Reverse conversion: Deciwatt to Kilowatt
1 dW × 0.0001 = 0.0001 kW
1 deciwatt = 0.0001 kilowatts.
kilowatts = deciwatts × 0.0001

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.
Understanding the Deciwatt (dW)
Deciwatt is 0.1 watt units.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

Frequently asked questions
How many deciwatts are in 1 kilowatt?
1 kilowatt equals 10,000 deciwatts, using the exact defined conversion factor rather than an estimate.
How do I convert kilowatt to deciwatt?
Multiply the kilowatt value by 10000. The converter above does this instantly to whatever precision you set.
How do I convert deciwatt back to kilowatt?
Use the reverse factor: 1 deciwatt equals 0.0001 kilowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilowatt?
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
What is a deciwatt?
Deciwatt (dW) is a unit of electricity.
Is the kilowatt to deciwatt conversion exact?
Yes. Both kilowatt and deciwatt are defined by fixed standards rather than physical artifacts, so the factor of 10000 used above is exact to as many digits as you choose to display.
Where is the kilowatt still used today?
Standard power unit worldwide for larger appliances, vehicles, and electrical systems
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
