Convert Megalitres per day to US gallons per second
Convert Megalitres per day (ML/d) to US gallons per second (gal/s) instantly and accurately.
Conversion Formula
gal/s = ML/d × 3.057546902
About Megalitres per day
The megalitre per day (ML/d) equals 1000/86400 ≈ 0.011574 m³/s, numerically identical to million litres per day. It is the preferred notation in Australian water-authority reporting, environmental flow assessments, and reservoir storage accounting. Murray-Darling Basin environmental flows are specified in ML/d; urban water utilities publish reservoir capacity and daily draw in ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
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.
