Flow Rate Converter
Convert volumetric flow between L/min, m³/h, GPM, CFM and more.
Flow rate — the volume of fluid moving past a point per unit time — shows up in plumbing, HVAC, irrigation and process engineering, each with its own favorite unit. Plumbers think in gallons per minute, HVAC engineers in cubic feet per minute, and the rest of the world in liters per minute or cubic meters per hour.
This converter translates any volumetric flow rate between L/s, L/min, m³/h, US and UK GPM and CFM, so pump specs, pipe sizing and airflow figures all line up regardless of which unit the datasheet used.
