Million standard cubic feet per day is a unit of measurement for gases that is predominantly used in the United States. It is frequently abbreviated MMSCFD. MMSCFD is commonly used as a measure of natural gas, liquefied petroleum gas (LPG), compressed natural gas (CNG) and other gases that extracted, processed or transported in high quantities.

A related measure is "mega standard cubic metres per day" (MSm3/d), which is equal to 106 Sm3/d used in many countries outside the United States.[1] One MMSCFD equals 1180 Sm3/h.

When converting to mass flowrate, the density of the gas should be used at Standard temperature and pressure.
