what is the difference between scf and ccf
Standard cubic foot In the natural gas industry where quantities are often expressed in standard cubic feet, large multiples of standard cubic feet are generally not expressed with Metric prefix, rather with prefixes based on roman numerals where the s for "standard" is often omitted. Common units of gas volumes include ccf (hundred standard cubic feet), Mcf (thousand standard cubic feet), MMcf (million standard cubic feet),.[3] The M refers to the Roman numeral for thousand,two M's would be one thousand thousand, or one million. Bcf (billion standard cubic feet), Tcf (trillion standard cubic feet), Qcf (quadrillion standard cubic feet), etc. are also used.
