About Converting US therms to Megajoules
US therm and Megajoule 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 megajoule is 1000000 joule units.
Formula
megajoules = us therms × 105.4804
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 megajoule equals 1000000 base units, so dividing one by the other gives the direct us therm-to-megajoule factor of 105.4804.
Simple example
1 therm × 105.4804 = 105.4804 MJ
1 us therm = 105.4804 megajoules.
Real-world example
100 therm × 105.4804 = 10,548.04 MJ
100 us therms = 10,548.04 megajoules.

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