About Converting Terawatts to Exawatts
Terawatt and Exawatt 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: 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
100 TW × 0.000001 = 0.0001 EW
100 terawatts = 0.0001 exawatts.

Reverse conversion: Exawatt to Terawatt
0.000001 EW × 1000000 = 1 TW
0.000001 exawatts = 1 terawatt.
terawatts = exawatts × 1000000

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 engineering.
What is a exawatt?
Exawatt (EW) is a unit of engineering.
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.
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.
