What is therm?


Approximately 105 megajoules. It's a common billing unit in the US.

Do they ever actually meter therms, or measure ccf and convert?
It seems to me to actually measure the therms, they'd need to
continuously monitor the heating value of the gas being delivered,
and that seems quite difficult compared with just measuring cf.
Of course, assuming they've stripped the gas down to nearly pure
methane, the conversion is easy, but natural gas can vary according
to ethane and higher content.
