What it means
Natural gas is a gas, so it is measured by the space it fills rather than by weight. One MCF is one thousand cubic feet of gas at standard temperature and pressure, and larger volumes are expressed as MMCF (one million cubic feet), BCF (one billion) and TCF (one trillion).
Mixing these up is one of the commonest errors in energy reporting. For a producer, MCF is the unit in which output, sales and costs all line up.
Revenue is volume sold multiplied by price per MCF, and lifting costs, transport fees and royalties are all quoted per MCF too. This lets managers compare a well in one field with a well in another.
Prices are often quoted in dollars per million British thermal units (a measure of heat energy) because gas from different sources has different energy content. A rough rule is that one MCF contains a little over one million British thermal units, so the price per MCF and the price per million units are similar but not identical.
Contracts will say which one applies. Investors in energy companies see MCF in reserve reports, which state how much gas can be recovered from known fields.
Analysts convert gas into oil-equivalent barrels so they can compare companies that produce a mix of both. A common conversion treats six MCF of gas as roughly equal in energy to one barrel of oil.
For a non-energy manager, the main lesson is to watch units. A cost of $1.20 per MCF applied to a volume stated in MMCF produces an error of a thousandfold, and such mistakes have appeared in budgets and contract reviews.
Accounting for gas also involves timing. Producers often record volumes on a delivered basis at the end of each month, while pipelines may allocate gas to wells later, so figures are revised after the first estimate.
Finance teams therefore expect small adjustments between the first reported MCF volume and the final settled figure.
In practice
Real-world examples.
Example
A small independent producer reports monthly output of 120,000 MCF. At a sale price of $2.50 per MCF the company books $300,000 of revenue. The finance team uses the same unit to track costs, so margin per MCF is easy to see.
Example
A utility signs a supply contract for 2,000,000 MCF a year. The purchasing manager checks the contract unit carefully because the supplier quotes the price per MMBtu, a unit of heat. She converts using the energy content stated in the agreement before comparing offers.
Example
A private equity analyst assesses an energy company with reserves of 30 BCF. She converts this to 30,000,000 MCF and applies a price assumption to estimate the value of what is in the ground. She then discounts the cash flows over the life of the field.
Formula
Calculation
Gas revenue = Volume in MCF x Price per MCF
Volume in MCF = Volume in MMCF x 1,000
Suppose a well produces 50,000 MCF in a month and the gas sells at $3.00 per MCF. Revenue is 50,000 x 3.00 = $150,000. If lifting and transport costs are $1.10 per MCF, the cost is 50,000 x 1.10 = $55,000, leaving a margin of 150,000 - 55,000 = $95,000. Expressed in MMCF, the same volume is 50,000 / 1,000 = 50 MMCF.Case study
Seen in the real world.
Prairie Wind Energy is an illustrative, fictional gas producer that supplies a regional utility. A new finance analyst built the annual budget and entered production of 4,500 MMCF as 4,500 MCF in one tab of the model.
The error understated revenue by a factor of one thousand in that tab. At a price of $3.00 per MCF the correct revenue was $13,500,000, while the model showed only $13,500.
The mistake was caught in the board pack review because the margin per MCF looked absurd. Prairie Wind added a units column to every volume cell, and the illustrative lesson is that a unit label costs nothing and prevents expensive errors.
Watch out
Common mistakes.
- Reading the M in MCF as million, when it stands for the Roman numeral one thousand, so MMCF is the million-unit.
- Applying a price per MCF to a volume stated in MMCF, which creates a thousandfold error in revenue or cost.
- Treating the price per MCF and the price per MMBtu as identical, when they differ because gas has varying energy content.
Questions
People also ask.
How do I convert MCF to cubic metres?
One MCF is about 28.3 cubic metres, since one cubic foot is about 0.0283 cubic metres.
What is the difference between MCF and MCFE?
MCFE means thousand cubic feet equivalent, a figure that converts oil and other liquids into an equivalent amount of gas for comparison.
Why do energy companies use MCF instead of weight?
Gas is easiest to meter by volume at a standard temperature and pressure, so volume is the practical unit for sales.
