Gallon per Minute to Liter per Hour Converter

Gallon per minute (gal/min or GPM) is a unit of volumetric flow rate representing the volume of fluid in gallons passing through a given area per minute. It's one of the most common flow rate units in American water and fluid systems.

The GPM unit became standard in American plumbing, water systems, and fluid handling applications. It provided convenient numerical values for residential and commercial water systems, becoming the primary unit for pump ratings, plumbing design, and water system specifications in the United States.

GPM is extensively used in American plumbing, water supply systems, pumps, and fluid handling equipment. It's standard for water pump ratings, plumbing fixture flow rates, irrigation systems, and residential/commercial water system design and specifications.

Liter per hour (L/h) is a unit of volumetric flow rate representing the volume of fluid in liters passing through a given area per hour. It's commonly used for slow, continuous processes and precision flow measurements.

The L/h unit became important in applications requiring precise, slow flow measurements such as medical infusions, chemical dosing, and precision manufacturing processes. It provided appropriate numerical values for applications where faster flow units would result in small decimal numbers.

L/h is used in medical infusion systems, chemical dosing equipment, precision manufacturing, and slow continuous processes. It's standard for IV pump settings, chemical feed systems, precision dispensing equipment, and laboratory analytical instruments.
