How to Convert m³/h to GPH
To convert m³/h to gph, multiply the flow rate by the following conversion ratio: 264.1720524 gph/cubic meters per hour.
Since one cubic meters per hour is equal to 264.1720524 gph, you can use this simple formula to convert:
The flow rate in gph is equal to the flow rate in m³/h multiplied by 264.1720524.
For example, here's how to convert 5 m³/h to gph using the formula above.
How Many GPH Are in a Cubic Meters per Hour?
There are 264.1720524 gph in a cubic meters per hour, which is why we use this value in the formula above.
Our cubic meters per hour 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/h and gph are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Meters per Hour?
A cubic meters per hour is a unit of flow rate equal to 16.6666667 liters per minute (L/min), the base unit for flow rate. Equal to 16.6667 L/min. [1]
The cubic meters per hour is classified as a metric and SI-compatible unit of flow rate. m³/h can be abbreviated as m³/h; for example, 1 cubic meters per hour can be written as 1 m³/h.
When working with m³/h (m³/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/h (m³/h) are widely used across standard flow rate applications within SI metric 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/h (m³/h) and gph (GPH), keep full floating-point precision (1 m³/h = 264.1720524 GPH; 1 GPH = 0.0037854 m³/h) during intermediate calculations and round only the final us gallons per hour figure to match your instrument tolerance.
