Convert US gallons per minute to US barrels per hour
Convert US gallons per minute (gpm) to US barrels per hour (bbl/h) instantly and accurately.
Conversion Formula
bbl/h = gpm × 1.428571429
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
About US barrels per hour
The US barrel per hour (bbl/h) equals 0.158987294928/3600 ≈ 4.416×10⁻⁵ m³/s, standard in petroleum-refinery process engineering for crude-oil unit feed rates and product run-downs. Crude-distillation unit (CDU) feed is sized in bbl/h; a 100 000 bbl/d refinery processes ≈4 167 bbl/h. Process simulation software (Aspen HYSYS) uses bbl/h by default for petroleum streams. 1 bbl/h ≈ 4.416×10⁻⁵ m³/s.
