About Converting Exajoules to US therms
Exajoule and US therm 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: Exajoule is 1000000000000000000 joule units, and uS therm used for natural gas energy.
Formula
us therms = exajoules × 9480434279.73
This factor comes from each unit's defined relationship to the category's base unit: 1 exajoule equals 1e+18 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct exajoule-to-us therm factor of 9480434279.73.
Simple example
1 EJ × 9480434280 = 9,480,434,280 therm
1 exajoule = 9,480,434,280 us therms.
Real-world example
100 EJ × 9480434280 = 948,043,428,000 therm
100 exajoules = 948,043,428,000 us therms.

Reverse conversion: US therm to Exajoule
1 therm × 1.054804e-10 = 1.054804e-10 EJ
1 us therm = 1.054804e-10 exajoules.
exajoules = us therms × 1.054804e-10

Frequently asked questions
How many us therms are in 1 exajoule?
1 exajoule equals 9,480,434,280 us therms, using the exact defined conversion factor rather than an estimate.
How do I convert exajoule to us therm?
Multiply the exajoule value by 9480434280. The converter above does this instantly to whatever precision you set.
How do I convert us therm back to exajoule?
Use the reverse factor: 1 us therm equals 1.054804e-10 exajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a exajoule?
Exajoule (EJ) is a unit of engineering.
What is a us therm?
US therm (therm) is a unit of engineering.
Is the exajoule to us therm conversion exact?
Yes. Both exajoule and us therm are defined by fixed standards rather than physical artifacts, so the factor of 9480434280 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.
