About Converting Terajoules to Exajoules
Terajoule and Exajoule 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: Terajoule is 1000000000000 joule units, and exajoule is 1000000000000000000 joule units.
Formula
exajoules = terajoules × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 terajoule equals 1e+12 base units, and 1 exajoule equals 1e+18 base units, so dividing one by the other gives the direct terajoule-to-exajoule factor of 0.000001.
Simple example
1 TJ × 0.000001 = 0.000001 EJ
1 terajoule = 0.000001 exajoules.
Real-world example
100 TJ × 0.000001 = 0.0001 EJ
100 terajoules = 0.0001 exajoules.

Reverse conversion: Exajoule to Terajoule
0.000001 EJ × 1000000 = 1 TJ
0.000001 exajoules = 1 terajoule.
terajoules = exajoules × 1000000

Frequently asked questions
How many exajoules are in 1 terajoule?
1 terajoule equals 0.000001 exajoules, using the exact defined conversion factor rather than an estimate.
How do I convert terajoule to exajoule?
Multiply the terajoule value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert exajoule back to terajoule?
Use the reverse factor: 1 exajoule equals 1,000,000 terajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a terajoule?
Terajoule (TJ) is a unit of engineering.
What is a exajoule?
Exajoule (EJ) is a unit of engineering.
Is the terajoule to exajoule conversion exact?
Yes. Both terajoule and exajoule 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.
