Q_std = Q_actual × (P_actual / P_std) × (T_std / T_actual), with absolute pressure and temperature. Assumes ideal gas behavior.
"Standard" means different things in different industries. Check which basis your datasheet, contract, or permit uses.
Gauge pressures (psig, barg) are converted to absolute using 1 atm.
