Gallon per Minute to Cubic Meter per Second 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 second (m³/s) is the SI unit of volumetric flow rate, representing the volume of fluid passing through a given cross-sectional area per unit time. One cubic meter per second equals 1,000 liters per second.

The m³/s unit was established with the International System of Units (SI) as the standard scientific unit for volumetric flow rate. It became essential for hydraulic engineering, fluid mechanics, and large-scale flow measurements in rivers, pipelines, and industrial systems.

M³/s is used in hydraulic engineering, river flow measurements, large pipeline systems, and scientific research. It's standard for measuring discharge rates of rivers, flow capacity of large pumps, and in fluid mechanics calculations for major water treatment and distribution systems.
