About US gallons per hour

The US gallon per hour (gph) equals 3.785411784×10⁻³/3600 ≈ 1.051×10⁻⁶ m³/s, common in oil-burner nozzle ratings, water-softener regeneration, and RV/marine-plumbing specifications. Residential oil-burner nozzles are rated in gph (e.g., 0.75 gph, 1.00 gph); a small boat bilge pump might handle 200-500 gph. 1 US gph ≈ 1.052×10⁻⁶ m³/s ≈ 3.785 L/h.

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.
