How to Convert m³/s to GPH

To convert m³/s to gph, multiply the flow rate by the following conversion ratio: 951,019.3884893 gph/cubic meters per second.

Since one cubic meters per second is equal to 951,019.3884893 gph, you can use this simple formula to convert:

gph = m³/s × 951,019.3884893

The flow rate in gph is equal to the flow rate in m³/s multiplied by 951,019.3884893.

For example, here's how to convert 5 m³/s to gph using the formula above.

gph = (5 m³/s × 951,019.3884893) = 4,755,096.9424467 GPH

How Many GPH Are in a Cubic Meters per Second?

There are 951,019.3884893 gph in a cubic meters per second, which is why we use this value in the formula above.

1 m³/s = 951,019.3884893 GPH|1 GPH = 0.000001052 m³/s

Our cubic meters per second to us gallons per hour calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

m³/s and gph 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 Hour?

A us gallons per hour is a unit of flow rate equal to 0.0630902 liters per minute (L/min), the base unit for flow rate. Equal to 1/60 GPM (0.06309 L/min). [2]

The us gallons per hour is classified as a US customary unit of flow rate. GPH can be abbreviated as GPH; for example, 1 us gallons per hour can be written as 1 GPH.

When working with gph (GPH) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, gph (GPH) 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 gph (GPH), keep full floating-point precision (1 m³/s = 951,019.3884893 GPH; 1 GPH = 0.000001052 m³/s) during intermediate calculations and round only the final us gallons per hour figure to match your instrument tolerance.
