For nearly a century, the electrical construction industry used the abbreviation "MCM" to designate a "thousand circular mils " in specifying thicknesses of large electrical cables . Since the mid-1990s, " kcmil " has been adopted as the "official" designation of a thousand circular mils, but the designation "MCM" still remains in wide use. A similar system is used in natural gas sales in the United States: m (or M) for thousands and mm (or MM) for millions of British thermal units or therms , and in the oil industry, [20] where 'MMbbl' is the symbol for 'millions of barrels'. This usage of the capital letter M for 'thousand' is from Roman numerals , in which M means 1,000. [21]
