Since the single letter M is now used commonly for one million because it is a metric prefix mega-, the use of MM or MMM is confusing and strongly discouraged. However, in Roman numeration, MM actually means 2000, not one million and MMM - 3000, not one billion. MMM for one billion is used in traditional units such as MMMBtu (one billion BTU), MMMcf (one billion cubic feet).
MM for one million can be seen in several traditional units such as MMBtu (one million BTU), MMcf (one million cubic feet). MMM is used for a billion which is a thousand cubed. MM is used for a million which is one thousand squared. In accounting, finance, oil and gas, and several other industries, M is sometimes used for a thousand from mille, which is the Roman numeral for a thousand. Metric prefixes are sometimes used with imperial and US customary units such as microinch and kilopound. Likewise, the prefix milli- may be added to gram to indicate division by one thousand one milligram is equal to one-thousandth of a gram (1 mg = 0.001 g). For example, the prefix mega- may be added to ton to indicate multiplication by one million one megaton is equal to one million tons (1 Mt = 1,000,000 t). Each prefix has a unique symbol that is added to the unit symbol. Metric prefixes are sometimes called SI prefixes.
