About Converting Centiwatts to Exawatts
Centiwatt and Exawatt 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: Centiwatt is 0.01 watt units, and exawatt is 1000000000000000000 watt units.
Formula
exawatts = centiwatts × 1e-20
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 exawatt equals 1e+18 base units, so dividing one by the other gives the direct centiwatt-to-exawatt factor of 1e-20.
Simple example
1 cW × 1e-20 = 1e-20 EW
1 centiwatt = 1e-20 exawatts.
Real-world example
120 cW × 1e-20 = 1.2e-18 EW
120 centiwatts = 1.2e-18 exawatts.

Reverse conversion: Exawatt to Centiwatt
1e-20 EW × 1e+20 = 1 cW
1e-20 exawatts = 1 centiwatt.
centiwatts = exawatts × 1e+20

Frequently asked questions
How many exawatts are in 1 centiwatt?
1 centiwatt equals 1e-20 exawatts, using the exact defined conversion factor rather than an estimate.
How do I convert centiwatt to exawatt?
Multiply the centiwatt value by 1e-20. The converter above does this instantly to whatever precision you set.
How do I convert exawatt back to centiwatt?
Use the reverse factor: 1 exawatt equals 1e+20 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 electricity.
What is a exawatt?
Exawatt (EW) is a unit of electricity.
Is the centiwatt to exawatt conversion exact?
Yes. Both centiwatt and exawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-20 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.
