Automatic calculator and gas flow units conversion relative to transit of gasses via Natural Gas Pipelines, from common areas/countries like Russia, Middle East, Asia and America or elsewhere, where the densities of the gas are measured at a specific Standard temperature and Standard pressure. The tool instantly converts a value of each gas flows rate quantity measurement into equivalent gas flow units alternative. Individual flow rate and flow by mass unit to unit menus.
You may enter whole numbers, decimals or fractions ie: 7, 29.35, 15 3/4.
The equation for manual calculations can be found at the bottom of this page.

Definition of the gas flow units used

MMSCFD - Million standard cubic feet of gas per day
SCFD - Standard cubic feet per day (gas)
SCFM - Standard cubic feet per minute (gas)
Sm^3/hr - Standard cubic metre per hour defined at 15 deg. C - 59°F - for US
Nm^3/hr - Normal cubic metre per hour defined at zero deg. C - 32°F - for countries using SI metric system of units
MSm^3/d - Mega Standard Cubic Metres per day defined at 15 deg. Celsius - 59° Fahrenheit - outside of US

The flow of gas per Million standard cubic feet of gas per day unit (MMSCFD) can be of course, mathematically, converted into broad varieties (in a large number) of other common flow units (MMSCFD to other flow uits).

Math equations used to manually calculate gas flow outcomes

MMSCFD to Sm3/h is calculated as:

Sm^3/hr of gas equals =

  MMSCFD * 1,000,000 * 288.15  
24 * 35.3147 * 288.81

Where:

288.15 = 15°C expressed in Kelvin (see below)

288.81 = 60°F expressed in Kelvin

24 = hours per day gas flow time

35.3147 = ft3 per m3

MMSCFD to Nm3/h is calculated as:

Nm^3/hr of gas equals =

  MMSCFD * 1,000,000 * 273.15  
24 * 35.3147 * 288.81

Where:

273.15 = 0°C expressed in Kelvin (see below)

288.81 = 60°F expressed in Kelvin

24 = hours per day gas flow time

35.3147 = ft3 per m3

Constants for the actual gas flow calculation
