Gas flow rate converter: MMscfd, Sm³/d

Convert gas flow rates between Sm³/d, Sm³/h, MMSm³/d, scf/d, Mscf/d, MMscf/d and Bscf/d.

Inputs

Use a decimal point or decimal comma, with no thousands separators. Scientific notation is accepted.

How it works

Enter a gas rate and its unit. MMscf/d means million standard cubic feet per day, and 1 MMscf/d = 28 316.85 Sm³/d.

Formula

1 MMscf/d = 28 316.85 Sm³/d = 1 179.87 Sm³/h

Assumptions and limits

Standard conditions are defined differently in different places (for example 15 °C and 1.01325 bar, or 60 °F and 14.696 psi). This converter turns cubic feet into cubic metres and days into hours and does not correct for a change of reference conditions; the difference is small (about 0.2 %) but matters for custody transfer.

For education and quick estimates only. Check the result against the applicable standards and your project data before using it in design, operation or safety decisions.
