About Converting Megajoules to US therms
Megajoule 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: Megajoule is 1000000 joule units, and uS therm used for natural gas energy.
Formula
us therms = megajoules × 0.00948043427973
This factor comes from each unit's defined relationship to the category's base unit: 1 megajoule equals 1000000 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct megajoule-to-us therm factor of 0.00948043427973.
Simple example
1 MJ × 0.00948043428 = 0.0094804343 therm
1 megajoule = 0.0094804343 us therms.
Real-world example
100 MJ × 0.00948043428 = 0.948043428 therm
100 megajoules = 0.948043428 us therms.

Frequently asked questions
How many us therms are in 1 megajoule?
1 megajoule equals 0.0094804343 us therms, using the exact defined conversion factor rather than an estimate.
How do I convert megajoule to us therm?
Multiply the megajoule value by 0.00948043428. The converter above does this instantly to whatever precision you set.
How do I convert us therm back to megajoule?
Use the reverse factor: 1 us therm equals 105.4804 megajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a megajoule?
Megajoule (MJ) is a unit of engineering.
What is a us therm?
US therm (therm) is a unit of engineering.
Is the megajoule to us therm conversion exact?
Yes. Both megajoule and us therm are defined by fixed standards rather than physical artifacts, so the factor of 0.00948043428 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.
