About Converting Exawatts to Terawatts
Exawatt and Terawatt 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: Exawatt is 1000000000000000000 watt units, and terawatt is 1000000000000 watt units.
Formula
terawatts = exawatts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 exawatt equals 1e+18 base units, and 1 terawatt equals 1e+12 base units, so dividing one by the other gives the direct exawatt-to-terawatt factor of 1000000.
Simple example
1 EW × 1000000 = 1,000,000 TW
1 exawatt = 1,000,000 terawatts.
Real-world example
100 EW × 1000000 = 100,000,000 TW
100 exawatts = 100,000,000 terawatts.

Frequently asked questions
How many terawatts are in 1 exawatt?
1 exawatt equals 1,000,000 terawatts, using the exact defined conversion factor rather than an estimate.
How do I convert exawatt to terawatt?
Multiply the exawatt value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert terawatt back to exawatt?
Use the reverse factor: 1 terawatt equals 0.000001 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 engineering.
What is a terawatt?
Terawatt (TW) is a unit of engineering.
Is the exawatt to terawatt conversion exact?
Yes. Both exawatt and terawatt are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
