About UK gallons per minute

The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.

About US barrels per day

The US barrel per day (bbl/d or bpd) equals 0.158987294928/86400 ≈ 1.840×10⁻⁶ m³/s, the universal unit for crude-oil production, refinery capacity, and petroleum-product supply/demand reporting. Saudi Arabia produces ≈9-10 million bbl/d; global demand is ≈99-102 million bbl/d. All oil-market pricing, OPEC quotas, and EIA reports use bbl/d. 1 bbl/d ≈ 1.840×10⁻⁶ m³/s ≈ 0.15899 m³/d.
