About Converting US therms to Centijoules
US therm and Centijoule 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 centijoule is 0.01 joule units.
Formula
centijoules = us therms × 10548040000
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 centijoule equals 0.01 base units, so dividing one by the other gives the direct us therm-to-centijoule factor of 10548040000.
Simple example
1 therm × 10548040000 = 10,548,040,000 cJ
1 us therm = 10,548,040,000 centijoules.
Real-world example
100 therm × 10548040000 = 1.054804e+12 cJ
100 us therms = 1.054804e+12 centijoules.
Conversion table
| US therm (therm) | Centijoule (cJ) |
|---|---|
| 1 therm | 10,548,040,000 cJ |
| 10 therm | 105,480,400,000 cJ |
| 50 therm | 527,402,000,000 cJ |
| 100 therm | 1.054804e+12 cJ |
| 500 therm | 5.27402e+12 cJ |
| 1,000 therm | 1.054804e+13 cJ |
Reverse conversion: Centijoule to US therm
1 cJ × 9.480434e-11 = 9.480434e-11 therm
1 centijoule = 9.480434e-11 us therms.
us therms = centijoules × 9.480434e-11

Frequently asked questions
How many centijoules are in 1 us therm?
1 us therm equals 10,548,040,000 centijoules, using the exact defined conversion factor rather than an estimate.
How do I convert us therm to centijoule?
Multiply the us therm value by 10548040000. The converter above does this instantly to whatever precision you set.
How do I convert centijoule back to us therm?
Use the reverse factor: 1 centijoule equals 9.480434e-11 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 centijoule?
Centijoule (cJ) is a unit of engineering.
Is the us therm to centijoule conversion exact?
Yes. Both us therm and centijoule are defined by fixed standards rather than physical artifacts, so the factor of 10548040000 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.
