About Converting Kilowatts to Centiwatts
Kilowatt and Centiwatt 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. Kilowatt is most often used for electric vehicle motor power ratings (alongside horsepower).
Formula
centiwatts = kilowatts × 100000
This factor comes from each unit's defined relationship to the category's base unit: 1 kilowatt equals 1000 base units, and 1 centiwatt equals 0.01 base units, so dividing one by the other gives the direct kilowatt-to-centiwatt factor of 100000.
Simple example
1 kW × 100000 = 100,000 cW
1 kilowatt = 100,000 centiwatts.
Real-world example
100 kW × 100000 = 10,000,000 cW
100 kilowatts = 10,000,000 centiwatts.
Conversion table
| Kilowatt (kW) | Centiwatt (cW) |
|---|---|
| 1 kW | 100,000 cW |
| 10 kW | 1,000,000 cW |
| 100 kW | 10,000,000 cW |
| 500 kW | 50,000,000 cW |
| 1,000 kW | 100,000,000 cW |
| 5,000 kW | 500,000,000 cW |
Reverse conversion: Centiwatt to Kilowatt
1 cW × 0.00001 = 0.00001 kW
1 centiwatt = 0.00001 kilowatts.
kilowatts = centiwatts × 0.00001

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 Centiwatt (cW)
Centiwatt is 0.01 watt units.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

Frequently asked questions
How many centiwatts are in 1 kilowatt?
1 kilowatt equals 100,000 centiwatts, using the exact defined conversion factor rather than an estimate.
How do I convert kilowatt to centiwatt?
Multiply the kilowatt value by 100000. The converter above does this instantly to whatever precision you set.
How do I convert centiwatt back to kilowatt?
Use the reverse factor: 1 centiwatt equals 0.00001 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 centiwatt?
Centiwatt (cW) is a unit of power.
Is the kilowatt to centiwatt conversion exact?
Yes. Both kilowatt and centiwatt are defined by fixed standards rather than physical artifacts, so the factor of 100000 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
