About Converting Microjoules to US therms
Microjoule 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: Microjoule is 0.000001 joule units, and uS therm used for natural gas energy.
Formula
us therms = microjoules × 9.480434e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 microjoule equals 0.000001 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct microjoule-to-us therm factor of 9.480434e-15.
Simple example
1 uJ × 9.480434e-15 = 9.480434e-15 therm
1 microjoule = 9.480434e-15 us therms.
Real-world example
100 uJ × 9.480434e-15 = 9.480434e-13 therm
100 microjoules = 9.480434e-13 us therms.

Frequently asked questions
How many us therms are in 1 microjoule?
1 microjoule equals 9.480434e-15 us therms, using the exact defined conversion factor rather than an estimate.
How do I convert microjoule to us therm?
Multiply the microjoule value by 9.480434e-15. The converter above does this instantly to whatever precision you set.
How do I convert us therm back to microjoule?
Use the reverse factor: 1 us therm equals 1.054804e+14 microjoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a microjoule?
Microjoule (uJ) is a unit of engineering.
What is a us therm?
US therm (therm) is a unit of engineering.
Is the microjoule to us therm conversion exact?
Yes. Both microjoule and us therm are defined by fixed standards rather than physical artifacts, so the factor of 9.480434e-15 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.
