About Converting US therms to Kilojoules
US therm and Kilojoule 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 kilojoule is 1000 joule units.
Formula
kilojoules = us therms × 105480.4
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 kilojoule equals 1000 base units, so dividing one by the other gives the direct us therm-to-kilojoule factor of 105480.4.
Simple example
1 therm × 105480.4 = 105,480.4 kJ
1 us therm = 105,480.4 kilojoules.
Real-world example
100 therm × 105480.4 = 10,548,040 kJ
100 us therms = 10,548,040 kilojoules.

Frequently asked questions
How many kilojoules are in 1 us therm?
1 us therm equals 105,480.4 kilojoules, using the exact defined conversion factor rather than an estimate.
How do I convert us therm to kilojoule?
Multiply the us therm value by 105480.4. The converter above does this instantly to whatever precision you set.
How do I convert kilojoule back to us therm?
Use the reverse factor: 1 kilojoule equals 0.0000094804 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 kilojoule?
Kilojoule (kJ) is a unit of engineering.
Is the us therm to kilojoule conversion exact?
Yes. Both us therm and kilojoule are defined by fixed standards rather than physical artifacts, so the factor of 105480.4 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.
