About Converting US therms to Megajoules
US therm and Megajoule 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 megajoule is 1000000 joule units.
Formula
megajoules = us therms × 105.4804
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 megajoule equals 1000000 base units, so dividing one by the other gives the direct us therm-to-megajoule factor of 105.4804.
Simple example
1 therm × 105.4804 = 105.4804 MJ
1 us therm = 105.4804 megajoules.
Real-world example
100 therm × 105.4804 = 10,548.04 MJ
100 us therms = 10,548.04 megajoules.
