About Converting US therms to Terajoules
US therm and Terajoule 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 terajoule is 1000000000000 joule units.
Formula
terajoules = us therms × 0.0001054804
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 terajoule equals 1e+12 base units, so dividing one by the other gives the direct us therm-to-terajoule factor of 0.0001054804.
Simple example
1 therm × 0.0001054804 = 0.0001054804 TJ
1 us therm = 0.0001054804 terajoules.
Real-world example
100 therm × 0.0001054804 = 0.01054804 TJ
100 us therms = 0.01054804 terajoules.
