how much is a unit of natural gas
Natural gas prices Depending on the marketplace, the price of natural gas is expressed in US dollars (or other currency) per 1 million British thermal units (MMBtu), thousand cubic feet (Mcf), or 1,000 cubic meters. Note that, for natural gas price comparisons, $ per MMBtu multiplied by 1.025 = $ per Mcf of pipeline-quality gas, which is what is delivered to consumers. For rough comparisons, one million Btu is approximately equal to a thousand cubic feet of natural gas.[6] Pipeline-quality gas has a BTU value slightly higher than that of pure methane, which has 1,012 BTU per cubic foot. Natural gas as it comes out of the ground is most often predominantly methane, but may have a wide range of BTU values, from much lower (due to dilution by non-hydrocarbon gasses) to much higher (due to the presence of ethane, propane, and heavier compounds) than standard pipeline-quality gas.[7]
