About Converting Gigawatts to Centiwatts
Gigawatt and Centiwatt 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. Specifically: Gigawatt is 1000000000 watt units, and centiwatt is 0.01 watt units.
Formula
centiwatts = gigawatts × 100000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gigawatt equals 1000000000 base units, and 1 centiwatt equals 0.01 base units, so dividing one by the other gives the direct gigawatt-to-centiwatt factor of 100000000000.
Simple example
1 GW × 100000000000 = 100,000,000,000 cW
1 gigawatt = 100,000,000,000 centiwatts.
Real-world example
120 GW × 100000000000 = 1.2e+13 cW
120 gigawatts = 1.2e+13 centiwatts.
Conversion table
| Gigawatt (GW) | Centiwatt (cW) |
|---|---|
| 1 GW | 100,000,000,000 cW |
| 5 GW | 500,000,000,000 cW |
| 12 GW | 1.2e+12 cW |
| 24 GW | 2.4e+12 cW |
| 120 GW | 1.2e+13 cW |
| 240 GW | 2.4e+13 cW |
Reverse conversion: Centiwatt to Gigawatt
1 cW × 1e-11 = 1e-11 GW
1 centiwatt = 1e-11 gigawatts.
gigawatts = centiwatts × 1e-11

Frequently asked questions
How many centiwatts are in 1 gigawatt?
1 gigawatt equals 100,000,000,000 centiwatts, using the exact defined conversion factor rather than an estimate.
How do I convert gigawatt to centiwatt?
Multiply the gigawatt value by 100000000000. The converter above does this instantly to whatever precision you set.
How do I convert centiwatt back to gigawatt?
Use the reverse factor: 1 centiwatt equals 1e-11 gigawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigawatt?
Gigawatt (GW) is a unit of electricity.
What is a centiwatt?
Centiwatt (cW) is a unit of electricity.
Is the gigawatt to centiwatt conversion exact?
Yes. Both gigawatt and centiwatt are defined by fixed standards rather than physical artifacts, so the factor of 100000000000 used above is exact to as many digits as you choose to display.
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.
