About Converting Gigajoules to US therms
Gigajoule 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: Gigajoule is 1000000000 joule units, and uS therm used for natural gas energy.
Formula
us therms = gigajoules × 9.48043427973
This factor comes from each unit's defined relationship to the category's base unit: 1 gigajoule equals 1000000000 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct gigajoule-to-us therm factor of 9.48043427973.
Simple example
1 GJ × 9.48043428 = 9.48043428 therm
1 gigajoule = 9.48043428 us therms.
Real-world example
100 GJ × 9.48043428 = 948.043428 therm
100 gigajoules = 948.043428 us therms.

Frequently asked questions
How many us therms are in 1 gigajoule?
1 gigajoule equals 9.48043428 us therms, using the exact defined conversion factor rather than an estimate.
How do I convert gigajoule to us therm?
Multiply the gigajoule value by 9.48043428. The converter above does this instantly to whatever precision you set.
How do I convert us therm back to gigajoule?
Use the reverse factor: 1 us therm equals 0.1054804 gigajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigajoule?
Gigajoule (GJ) is a unit of engineering.
What is a us therm?
US therm (therm) is a unit of engineering.
Is the gigajoule to us therm conversion exact?
Yes. Both gigajoule and us therm are defined by fixed standards rather than physical artifacts, so the factor of 9.48043428 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.
