About Converting Terajoules to US therms
Terajoule 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: Terajoule is 1000000000000 joule units, and uS therm used for natural gas energy.
Formula
us therms = terajoules × 9480.43427973
This factor comes from each unit's defined relationship to the category's base unit: 1 terajoule equals 1e+12 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct terajoule-to-us therm factor of 9480.43427973.
Simple example
1 TJ × 9480.43428 = 9,480.43428 therm
1 terajoule = 9,480.43428 us therms.
Real-world example
100 TJ × 9480.43428 = 948,043.428 therm
100 terajoules = 948,043.428 us therms.

Frequently asked questions
How many us therms are in 1 terajoule?
1 terajoule equals 9,480.43428 us therms, using the exact defined conversion factor rather than an estimate.
How do I convert terajoule to us therm?
Multiply the terajoule value by 9480.43428. The converter above does this instantly to whatever precision you set.
How do I convert us therm back to terajoule?
Use the reverse factor: 1 us therm equals 0.0001054804 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 us therm?
US therm (therm) is a unit of engineering.
Is the terajoule to us therm conversion exact?
Yes. Both terajoule and us therm are defined by fixed standards rather than physical artifacts, so the factor of 9480.43428 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.
