About Converting Terajoules to US therms
Terajoule and US therm both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Terajoule is 1000000000000 joule units, and uS therm used for natural gas energy.
Formula
us therms = terajoules × 9480.43427973
This factor comes from each unit's defined relationship to the category's base unit: 1 terajoule equals 1e+12 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct terajoule-to-us therm factor of 9480.43427973.
Simple example
1 TJ × 9480.43428 = 9,480.43428 therm
1 terajoule = 9,480.43428 us therms.
Real-world example
100 TJ × 9480.43428 = 948,043.428 therm
100 terajoules = 948,043.428 us therms.
