Cubic Meter per Second to Cubic Meter per Day (m³/s to m³/d)
Convert m³/s to m³/d — Flow Rate converter
Also written as m3/s to m3/d.
One cubic meter per second equals 86400 m³/d, so to convert cubic meters per second to cubic meters per day you multiply the value by 86400. A cubic meter per second is larger than a cubic meter per day — going the other way, 1 m³/d = 0.0000115741 m³/s. For example, 10 m³/s = 864000 m³/d and 50 m³/s = 4320000 m³/d.
1 m³/s = 86400 m³/d
Cubic Meter per Second to Cubic Meter per Day formula
1 Cubic Meter per Second = 86400 m³/d
Worked examples
- 25 m³/s = 2160000 m³/d
- 100 m³/s = 8640000 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 m³/s = 86400 m³/d.
