About Converting US therms to Petajoules
US therm and Petajoule 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 petajoule is 1000000000000000 joule units.
Formula
petajoules = us therms × 1.054804e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 petajoule equals 1e+15 base units, so dividing one by the other gives the direct us therm-to-petajoule factor of 1.054804e-7.
Simple example
1 therm × 1.054804e-7 = 1.054804e-7 PJ
1 us therm = 1.054804e-7 petajoules.
Real-world example
100 therm × 1.054804e-7 = 0.000010548 PJ
100 us therms = 0.000010548 petajoules.
