Default Natural gas usage

I am working on a air emissions report for the Mo. DNR. I need to convert Therms to CCF (100 cu. ft.), can you help with a formula?

Thanks
Jim

I Googled and found data showing:
1 cubic foot of natural gas = 1,031 Btu

100 cubic foot of natural gas = 100 * 1031 = 103,100 Btu

A therm is 100,000 Btu so:
103,100 Btu / 100,000 = 1.031 therm

Therefore, the formulas you are looking for are:

therm / 1.031 = CCF
CCF * 1.031 = therm

It is very close to a 1 to 1 conversion. For most things you could just estimate 1 therm = 1 CCF.

If a Therm is 100,000 btu and a ccf is a 1000 btu, where is the one to one conversion? 1 therm is about 100 ccf not 1 ccf.

Note that "CCF" stands for 100 cubic feet, not 1 cubic foot. The first 'C' is the Roman numeral C, which stands for 100.

Then, using the information in Post #2,
1 CCF = 100 cubic feet = 100 * 1031 BTU = 103,100 BTU
not 1000 BTU as you wrote.

Since a therm is 100,000 BTU, this is nearly the same as 1 CCF. More precisely,
1 CCF = 103,100 BTU = 1.031 therm

Could someone also come up with a formula that will convert ccf's to cubic ft?

So there's no way to convert it to cubic feet?

Blondsrus, see Roy's response from below:

So what is a better price to pay for natural gas:
$1.569 per ccf or $1.249 per therm ?
(not good at math)
