* In [[natural gas]] pricing, the Canadian definition is that {{val|1000000|u=Btu|fmt=commas}} ≡ {{val|1.054615|u=GJ}}.<ref name=Alberta>{{cite web | url=http://www.energy.gov.ab.ca/about_us/1132.asp | title=Energy Measurements | access-date=7 January 2017 | publisher=Government of Alberta Province | url-status=dead | archive-url=https://web.archive.org/web/20170120191331/http://www.energy.gov.ab.ca/About_Us/1132.asp | archive-date=20 January 2017 | df=dmy-all }}</ref>
* The energy content (high or low heating value) of a volume of natural gas varies with the composition of the natural gas, which means there is no universal conversion factor for energy to volume. {{convert|1|ft3|L|abbr=off}} of average natural gas yields ≈ 1,030&nbsp;Btu (between 1,010&nbsp;Btu and 1,070&nbsp;Btu, depending on quality, when burned)
* As a coarse approximation, {{convert|1000|ft3|m3}} of natural gas yields ≈ {{val|1000000|u=Btu|fmt=commas}} ≈ {{val|1|u=GJ}}.
* For natural gas price conversion {{val|1000|u=m3|fmt=commas}} ≈ 36.9&nbsp;million&nbsp;Btu and {{val|1000000|u=Btu|fmt=commas}} ≈ {{val|27.1|u=m3}}
