About Converting US therms to Terajoules
US therm and Terajoule 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: US therm used for natural gas energy, and terajoule is 1000000000000 joule units.
Formula
terajoules = us therms × 0.0001054804
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 terajoule equals 1e+12 base units, so dividing one by the other gives the direct us therm-to-terajoule factor of 0.0001054804.
Simple example
1 therm × 0.0001054804 = 0.0001054804 TJ
1 us therm = 0.0001054804 terajoules.
Real-world example
100 therm × 0.0001054804 = 0.01054804 TJ
100 us therms = 0.01054804 terajoules.

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