Convert Acre-feet per hour to Millilitres per minute
Convert Acre-feet per hour (ac-ft/h) to Millilitres per minute (mL/min) instantly and accurately.
Conversion Formula
mL/min = ac-ft/h × 20558030.63
About Acre-feet per hour
The acre-foot per hour (ac-ft/h) equals 1233.48183754752/3600 ≈ 0.34263 m³/s, standard for sizing irrigation district delivery canals, reservoir outflow scheduling, and aquifer recharge basin calculations in the western US. The US Bureau of Reclamation uses ac-ft/h for canal operational planning; a 1 000-acre farm irrigating with 0.5 in/h rain-equivalent receives ≈41 ac-ft/h. 1 ac-ft/h ≈ 0.34263 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.
