About Converting US therms to Decajoules
US therm and Decajoule both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: US therm used for natural gas energy, and decajoule is 10 joule units.
Formula
decajoules = us therms × 10548040
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 decajoule equals 10 base units, so dividing one by the other gives the direct us therm-to-decajoule factor of 10548040.
Simple example
1 therm × 10548040 = 10,548,040 daJ
1 us therm = 10,548,040 decajoules.
Real-world example
100 therm × 10548040 = 1,054,804,000 daJ
100 us therms = 1,054,804,000 decajoules.
