Conversion Formula

bbl/d = qt/min × 8.571428571

About US quarts per minute

The US quart per minute (qt/min) equals 3.785411784×10⁻³/4/60 ≈ 1.577×10⁻⁵ m³/s, encountered in US small-engine fuel system testing and food-processing pump calibration. Engine dynamometer fuel-flow instrumentation sometimes uses qt/min when testing small gasoline engines consuming 1-6 qt/min at full load. 1 US qt/min ≈ 1.577×10⁻⁵ m³/s.

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.
