V2 = 156.58 nm3/hr (gives great nm3/h which is less < than the sm3/h) Now, using the equation PV=nRT for the both states, knowing that the P, n and R remains constant the equation can be written as follows:Īssuming condition 1 is at standard conditions (15✬, 288.15K), and condition 2 is at normal conditions (0✬, 273.15K), the gas volume based flow rate can be converted as follows: So, lets look at an example:Ī gas well produces natural gas at a flow rate of 140 000 SCFD (standard cubic feet per day) at a stable state:ġ40 000 SCFD = 3964.352 sm3/day = 165.18 sm3/hr (this online gas flow converter gives very accurate sm3/hr readings, and for other gas transfer units it contains - without rounding errors.) Therefore a certain mass of gas will have a smaller volume at normal conditions as apposed to standard conditions. Firstly when comparing a gas at the same pressures and at different temperatures, the density increases as the temperature decreases. Both conditions are at atmospheric pressure (1 atm or 101.325 kPa) with standard referring to 15✬ and normal to 0✬ gas temperature. The S and N letter obviously refers to the gas condition (standard and normal). ![]() Whilst the actual converter uses complete numbers for the correct calculated output. Please note that some numbers in these mathematical examples are rounded.

On average one standard cubic foot of natural gas yields 1,040 Btu (calculated between low 1,010 Btu and high 1,070 Btu - depends on its composition when the gas is burned.) No universal gas volume-to-energy conversion factor has been established because a high/low heating value (gas energy content) comes down to the gas quality. Traditionally the MMBtu is used in pricing of natural gas. MMBtu - One Million British thermal units - pricing unit for gas energy. MSm^3/d - Mega Standard Cubic Metres per day defined at 15 deg. C - 32☏ - for countries using SI metric system of units Nm^3/hr - Normal cubic metre per hour defined at zero deg. Sm^3/hr - Standard cubic metre per hour defined at 15 deg. SCFM - Standard cubic feet per minute (gas) MMSCFD - Million standard cubic feet of gas per day - a common volume of gas measure (unit abbreviation MMscf) The equation for manual calculations can be found at the bottom of this page. You may enter whole numbers, decimals or fractions ie: 7, 29.35, 15 3/4. Individual flow rate and flow by mass unit to unit menus. The tool instantly converts a value of each gas flows rate quantity measurement into equivalent gas flow units alternative. Where the densities of the gas are measured at a specific Standard temperature and Standard pressure. Automatic calculator and gas flow units conversion relative to transit of gasses via gas pipes and Natural Gas Pipelines from common areas/countries like in America, Asia, Middle East or elsewhere.
