Gallon (US) per Hour to Cubic Meter per Day (gal/h to m³/d)
Convert gal/h to m³/d — Flow Rate converter
Also written as gal/h to m3/d.
One gallon (US) per hour equals 0.09084988 m³/d, so to convert gallons (US) per hour to cubic meters per day you multiply the value by 0.09084988. A gallon (US) per hour is smaller than a cubic meter per day — going the other way, 1 m³/d = 11.007169 gal/h. For example, 10 gal/h = 0.90849883 m³/d and 50 gal/h = 4.542494 m³/d.
1 gal/h = 0.09084988 m³/d
Gallon (US) per Hour to Cubic Meter per Day formula
1 Gallon (US) per Hour = 0.09084988 m³/d
Worked examples
- 25 gal/h = 2.271247 m³/d
- 100 gal/h = 9.084988 m³/d

Which gallon, and which trade
The single most expensive mistake in flow conversion is the gallon. A US liquid gallon is 3.785411784 litres; an imperial gallon is 4.54609 litres. US GPM and imperial GPM differ by about 20%, and pump datasheets frequently do not say which one they mean. Check the manufacturer's country of origin before trusting a GPM figure.
Different trades default to different units for the same physical quantity: HVAC and compressed air work in CFM, plumbing and pumps in GPM or LPM, and process and water engineering in m³/h or L/s. A specification that mixes them is usually quoting different equipment, not different flows. On this page, 1 gal/h = 0.09084988 m³/d.
