How to Convert m³/s to GPM
To convert m³/s to gpm, multiply the flow rate by the following conversion ratio: 15,850.3231415 gpm/cubic meters per second.
Since one cubic meters per second is equal to 15,850.3231415 gpm, you can use this simple formula to convert:
The flow rate in gpm is equal to the flow rate in m³/s multiplied by 15,850.3231415.
For example, here's how to convert 5 m³/s to gpm using the formula above.
How Many GPM Are in a Cubic Meters per Second?
There are 15,850.3231415 gpm in a cubic meters per second, which is why we use this value in the formula above.
Our cubic meters per second to us gallons per minute calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
m³/s and gpm are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Meters per Second?
A cubic meters per second is a unit of flow rate equal to 60,000 liters per minute (L/min), the base unit for flow rate. Coherent SI flow unit equal to 1,000 L/s (60,000 L/min). [1]
The cubic meters per second is classified as an International System of Units (SI) unit of flow rate. m³/s can be abbreviated as m³/s; for example, 1 cubic meters per second can be written as 1 m³/s.
When working with m³/s (m³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/s (m³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a US Gallons per Minute?
A us gallons per minute is a unit of flow rate equal to 3.7854118 liters per minute (L/min), the base unit for flow rate. Standard US plumbing & pump flow rate (3.78541 L/min). [2]
The us gallons per minute is classified as a US customary unit of flow rate. GPM can be abbreviated as GPM; for example, 1 us gallons per minute can be written as 1 GPM.
When working with gpm (GPM) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gpm (GPM) are widely used across standard flow rate applications within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between m³/s (m³/s) and gpm (GPM), keep full floating-point precision (1 m³/s = 15,850.3231415 GPM; 1 GPM = 0.00006309 m³/s) during intermediate calculations and round only the final us gallons per minute figure to match your instrument tolerance.
