In order to convert $/cubic foot for natural gas into $/therm, which are the gas cost units in THERM, do the following conversion:

Multiply the cost of the natural gas in cubic feet ($/cubic feet) times 0.01 to get cost per Therm ($/Therm)

Background:

1 cubic foot of natural gas = 1,000 Btus

1 Therm = 100,000 Btus

Therefore:

1 Therm = 100 cubic feet of natural gas

or

1 cubic foot of natural gas = 0.01 Therm

Example:

$0.10 / cubic foot of natural gas = $0.001 / Therm
