About Converting US therms to Kilojoules
US therm and Kilojoule 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 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.
