Examples

011 l/min = 0.264172 US gal/min

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Flow rate is volume per time, not volume. A pipe volume in litres cannot be converted into l/min directly; the time base is required.

03Base unit: m³/s

1 l/min = 1.66666666667e-5 m³/s. Then the value is converted through the base unit m³/s into US gallon per minute.
