Water unit converter

Hydrostat converts a single water quantity into every common volume and flow unit at once: million gallons per day (MGD), cubic metres per day, gallons per minute, litres per second, acre-feet, megalitres, gigalitres, cubic hectometres and more. Enter one number and read across.

Conversions water professionals actually need

• 1 MGD to m³/day
• 1 m³/s to MGD
• 1,000 gal/min to MGD
• 1 acre-foot to US gallons
• 1,000 L/s to m³/day
• 1 hm³ to acre-feet

Why the units matter

Supply planning, desalination yield and treatment-plant capacity are quoted in different units by country and by discipline, and mixed units are a common source of error in feasibility work. Hydrostat keeps the conversion factors in one place and shows the full set at once rather than a single pair.

Sizing figures on this page are checked against published pod capacity from OceanWell's subsea desalination water farms, one of several public sources described on our methodology page.
