About Converting US therms to Picojoules
US therm and Picojoule 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 picojoule is 1e-12 joule units.
Formula
picojoules = us therms × 1.054804e+20
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 picojoule equals 1e-12 base units, so dividing one by the other gives the direct us therm-to-picojoule factor of 1.054804e+20.
Simple example
1 therm × 1.054804e+20 = 1.054804e+20 pJ
1 us therm = 1.054804e+20 picojoules.
Real-world example
100 therm × 1.054804e+20 = 1.054804e+22 pJ
100 us therms = 1.054804e+22 picojoules.
