SCFM to ACFM Conversion Formula

ACFM = SCFM x 14.696 / (Pa + 14.696) x degrees F / 530

Where as:

ACFM = Actual Cubic Feet per Minute measured gas flow

SCFM = Standard Cubic Feet per Minute gas flow

Pa = Operating Pressure in (PSIA) = PSIG + 14.696

Ta = Temperature in degrees Rankine = F + 460

Note: All calculations are at sea level.

What is 14.696

we are using Absolute Pressure Pa in the formula,
say if we have Gauge Pressure Psig, then we need to add this constant to get pressure in Pa
