About UK gallons per hour

The UK gallon per hour (gph) equals 4.54609×10⁻³/3600 ≈ 1.263×10⁻⁶ m³/s, found in pre-metric British burner-nozzle ratings, oil-consumption logs for diesel generators, and ship fuel-economy records. British aviation fuel consumption was once published in UK gal/h; legacy Lloyd's Register tanker descriptions used UK gal/h for cargo pump capacities. 1 UK gph ≈ 1.263×10⁻⁶ m³/s.

About US barrels per second

The US barrel per second (bbl/s) equals 0.158987294928 m³/s, an extremely large flow rate used only for catastrophic spill-rate estimates and very large pipeline surge calculations. The 2010 Deepwater Horizon spill peaked at ≈60 000 bbl/d ≈ 0.000694 bbl/s; major subsea pipeline ruptures may briefly exceed 1 bbl/s during decompression. 1 US bbl/s = 0.158987 m³/s ≈ 158.987 L/s.
