Frequently asked questions
What units does this flow converter support?
It supports 15 units: Cubic meter/second (m³/s), Cubic meter/minute (m³/min), Cubic meter/hour (m³/h), Liter/second (L/s), Liter/minute (L/min), Liter/hour (L/h), Cubic foot/second (ft³/s), Cubic foot/minute (CFM) (CFM), Cubic foot/hour (ft³/h), Gallon (US)/minute (GPM), Gallon (US)/hour (GPH), Gallon (US)/day (GPD), Gallon (UK)/minute (GPM (UK)), Oil barrel/day (bbl/d), Million gallons (US)/day (MGD).
What is the base unit of flow?
The SI reference unit is the cubic meter/second (m³/s). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
