Gallon per Minute to Cubic Meter 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.

Cubic meter per hour (m³/h) is a unit of volumetric flow rate representing the volume of fluid passing through a given area in one hour. It provides a convenient scale for continuous process measurements and system capacity ratings.

The m³/h unit became important with the development of continuous industrial processes and utility systems where hourly flow measurements were more practical than per-second or per-minute rates. It was particularly useful for water supply, gas distribution, and chemical processing.

M³/h is extensively used in water supply systems, gas distribution networks, chemical processing, and building services. It's standard for water meter readings, gas flow measurements, pump capacity ratings, and continuous process flow monitoring in industrial applications.
