About Converting Centiwatts to Gigawatts
Centiwatt and Gigawatt 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 gigawatt is 1000000000 watt units.
Formula
gigawatts = centiwatts × 1e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 gigawatt equals 1000000000 base units, so dividing one by the other gives the direct centiwatt-to-gigawatt factor of 1e-11.
Simple example
1 cW × 1e-11 = 1e-11 GW
1 centiwatt = 1e-11 gigawatts.
Real-world example
100 cW × 1e-11 = 1e-9 GW
100 centiwatts = 1e-9 gigawatts.
Conversion table
| Centiwatt (cW) | Gigawatt (GW) |
|---|---|
| 1 cW | 1e-11 GW |
| 10 cW | 1e-10 GW |
| 50 cW | 5e-10 GW |
| 100 cW | 1e-9 GW |

Reverse conversion: Gigawatt to Centiwatt
1e-11 GW × 100000000000 = 1 cW
1e-11 gigawatts = 1 centiwatt.
centiwatts = gigawatts × 100000000000

Frequently asked questions
How many gigawatts are in 1 centiwatt?
1 centiwatt equals 1e-11 gigawatts, using the exact defined conversion factor rather than an estimate.
How do I convert centiwatt to gigawatt?
Multiply the centiwatt value by 1e-11. The converter above does this instantly to whatever precision you set.
How do I convert gigawatt back to centiwatt?
Use the reverse factor: 1 gigawatt equals 100,000,000,000 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 gigawatt?
Gigawatt (GW) is a unit of engineering.
Is the centiwatt to gigawatt conversion exact?
Yes. Both centiwatt and gigawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-11 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.
