Convert US pints per hour to Millilitres per minute
Convert US pints per hour (pt/h) to Millilitres per minute (mL/min) instantly and accurately.
Conversion Formula
mL/min = pt/h × 7.88627455
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 Millilitres per minute
The millilitre per minute (mL/min) equals 10⁻⁶/60 ≈ 1.667×10⁻⁸ m³/s, the standard flow rate unit for HPLC and preparative chromatography. A reverse-phase HPLC column (4.6 mm i.d.) operates at 1-2 mL/min; a cardiac output catheter measures 4 000-8 000 mL/min (= L/min). 1 mL/min ≈ 1.667×10⁻⁸ m³/s = 60 mL/h.
