About Converting Terawatts to Exawatts
Terawatt 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: Terawatt is 1000000000000 watt units, and exawatt is 1000000000000000000 watt units.
Formula
exawatts = terawatts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 exawatt equals 1e+18 base units, so dividing one by the other gives the direct terawatt-to-exawatt factor of 0.000001.
Simple example
1 TW × 0.000001 = 0.000001 EW
1 terawatt = 0.000001 exawatts.
Real-world example
120 TW × 0.000001 = 0.00012 EW
120 terawatts = 0.00012 exawatts.

Frequently asked questions
How many exawatts are in 1 terawatt?
1 terawatt equals 0.000001 exawatts, using the exact defined conversion factor rather than an estimate.
How do I convert terawatt to exawatt?
Multiply the terawatt value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert exawatt back to terawatt?
Use the reverse factor: 1 exawatt equals 1,000,000 terawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a terawatt?
Terawatt (TW) is a unit of electricity.
What is a exawatt?
Exawatt (EW) is a unit of electricity.
Is the terawatt to exawatt conversion exact?
Yes. Both terawatt and exawatt are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
