About Converting Centiwatts to Kilowatts
Centiwatt and Kilowatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Centiwatt is 0.01 watt units, and kilowatt is 1000 watt units.
Formula
kilowatts = centiwatts × 0.00001
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 kilowatt equals 1000 base units, so dividing one by the other gives the direct centiwatt-to-kilowatt factor of 0.00001.
Simple example
1 cW × 0.00001 = 0.00001 kW
1 centiwatt = 0.00001 kilowatts.
Real-world example
100 cW × 0.00001 = 0.001 kW
100 centiwatts = 0.001 kilowatts.
Conversion table
| Centiwatt (cW) | Kilowatt (kW) |
|---|---|
| 1 cW | 0.00001 kW |
| 10 cW | 0.0001 kW |
| 50 cW | 0.0005 kW |
| 100 cW | 0.001 kW |
| 500 cW | 0.005 kW |
| 1,000 cW | 0.01 kW |
Reverse conversion: Kilowatt to Centiwatt
0.00001 kW × 100000 = 1 cW
0.00001 kilowatts = 1 centiwatt.
centiwatts = kilowatts × 100000

Understanding the Centiwatt (cW)
Centiwatt is 0.01 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 centiwatt?
1 centiwatt equals 0.00001 kilowatts, using the exact defined conversion factor rather than an estimate.
How do I convert centiwatt to kilowatt?
Multiply the centiwatt value by 0.00001. The converter above does this instantly to whatever precision you set.
How do I convert kilowatt back to centiwatt?
Use the reverse factor: 1 kilowatt equals 100,000 centiwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a centiwatt?
Centiwatt (cW) is a unit of engineering.
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 centiwatt to kilowatt conversion exact?
Yes. Both centiwatt and kilowatt are defined by fixed standards rather than physical artifacts, so the factor of 0.00001 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
