About Converting Exawatts to Petawatts
Exawatt and Petawatt 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: Exawatt is 1000000000000000000 watt units, and petawatt is 1000000000000000 watt units.
Formula
petawatts = exawatts × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 exawatt equals 1e+18 base units, and 1 petawatt equals 1e+15 base units, so dividing one by the other gives the direct exawatt-to-petawatt factor of 1000.
Simple example
1 EW × 1000 = 1,000 PW
1 exawatt = 1,000 petawatts.
Real-world example
120 EW × 1000 = 120,000 PW
120 exawatts = 120,000 petawatts.

Frequently asked questions
How many petawatts are in 1 exawatt?
1 exawatt equals 1,000 petawatts, using the exact defined conversion factor rather than an estimate.
How do I convert exawatt to petawatt?
Multiply the exawatt value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert petawatt back to exawatt?
Use the reverse factor: 1 petawatt equals 0.001 exawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a exawatt?
Exawatt (EW) is a unit of electricity.
What is a petawatt?
Petawatt (PW) is a unit of electricity.
Is the exawatt to petawatt conversion exact?
Yes. Both exawatt and petawatt are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
