Cubic Meter per Hour to Milliliter per Second (m³/h to mL/s)
Convert m³/h to mL/s — Flow Rate converter
Also written as m3/h to mL/s.
One cubic meter per hour equals 277.777778 mL/s, so to convert cubic meters per hour to milliliters per second you multiply the value by 277.777778. A cubic meter per hour is larger than a milliliter per second — going the other way, 1 mL/s = 0.0036 m³/h. For example, 10 m³/h = 2777.78 mL/s and 50 m³/h = 13888.89 mL/s.
1 m³/h = 277.777778 mL/s

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/h = 277.777778 mL/s.
