Conversion Formula
gal/s = pt/h × 3.472222222e-5
About US pints per hour
The US pint per hour (pt/h) equals 3.785411784×10⁻³/8/3600 ≈ 1.314×10⁻⁷ m³/s, used in US medical-device standards for slow-drip infusion and in American homebrew calculations for sparge water addition rates. A slow gravity sparge at 24 pt/h = 3 US gal/h is typical for small-batch homebrewing. 1 US pt/h ≈ 1.314×10⁻⁷ m³/s.
About US gallons per second
The US gallon per second (gal/s) equals 3.785411784×10⁻³ m³/s, used for very large pump discharge rates and fire-suppression deluge systems. A large centrifugal fire pump rated 1 500 US gal/min delivers exactly 25 US gal/s; industrial cooling-tower makeup lines are sized in gal/s at peak demand. 1 US gal/s = 3.785411784×10⁻³ m³/s = 60 US gal/min ≈ 227.1 L/min.
