CCF vs Therms: What’s the Difference?

CCF and therms are both commonly used to measure natural gas usage, but they represent different things.

CCF is a volume measurement: 1 CCF equals 100 cubic feet of gas. A therm is an energy measurement (heat content).

Because the energy content of gas can vary by region and utility (BTU per cubic foot), converting CCF to therms is typically done using a utility-provided conversion factor.

CCF to Therms Conversion Formula

To convert CCF to therms, multiply CCF by your therms-per-CCF factor. Many utilities publish this factor on your bill or website.

CCF to therms =
therms = CCF × (therms per CCF)

The (therms per CCF) factor depends on your gas heat content and utility.

Therms to CCF =
CCF = therms ÷ (therms per CCF)

Reverse the conversion using the same factor.

CCF
= Gas volume in hundred cubic feet (100 ft³)
therms
= Gas energy usage in therms
therms per CCF
= Utility conversion factor (often around ~1.0, but varies)
Example (using a sample factor)
50 CCF × 1.03 = 51.5 therms

If your utility uses 1.03 therms per CCF, 50 CCF equals 51.5 therms.

Reverse example
51.5 therms ÷ 1.03 = 50 CCF

Convert therms back to CCF using the same factor.

Frequently Asked Questions

How do you convert CCF to therms?

Use therms = CCF × (therms per CCF). The factor depends on your utility’s heat content conversion.

How many CCF in a therm?

It depends on the therms-per-CCF factor. If 1 CCF ≈ 1.03 therms, then 1 therm ≈ 0.971 CCF (1 ÷ 1.03).

Why isn’t there one fixed CCF to therms number?

Because therms measure energy and CCF measures volume, and the energy content per cubic foot can vary by gas composition and region.

Is this a CCF to therms calculator?

Yes. This CCF to therms calculator converts CCF to therms using a configurable conversion factor.

Can I convert therms back to CCF?

Yes. Use CCF = therms ÷ (therms per CCF).
