About Converting Millijoules to US therms
Millijoule and US therm both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Millijoule is 0.001 joule units, and uS therm used for natural gas energy.
Formula
us therms = millijoules × 9.480434e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 millijoule equals 0.001 base units, and 1 us therm equals 105480400 base units, so dividing one by the other gives the direct millijoule-to-us therm factor of 9.480434e-12.
Simple example
1 mJ × 9.480434e-12 = 9.480434e-12 therm
1 millijoule = 9.480434e-12 us therms.
Real-world example
100 mJ × 9.480434e-12 = 9.480434e-10 therm
100 millijoules = 9.480434e-10 us therms.
