How to Convert m³/h to GPD
To convert m³/h to gpd, multiply the flow rate by the following conversion ratio: 6,340.1292566 gpd/cubic meters per hour.
Since one cubic meters per hour is equal to 6,340.1292566 gpd, you can use this simple formula to convert:
The flow rate in gpd is equal to the flow rate in m³/h multiplied by 6,340.1292566.
For example, here's how to convert 5 m³/h to gpd using the formula above.
How Many GPD Are in a Cubic Meters per Hour?
There are 6,340.1292566 gpd 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 day calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
m³/h and gpd 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 Day?
A us gallons per day is a unit of flow rate equal to 0.0026288 liters per minute (L/min), the base unit for flow rate. Water treatment flow unit. [2]
The us gallons per day is classified as a US customary unit of flow rate. GPD can be abbreviated as GPD; for example, 1 us gallons per day can be written as 1 GPD.
When working with gpd (GPD) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gpd (GPD) are widely used across fine-tolerance laboratory, analytical, and micro-scale flow rate measurements within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between m³/h (m³/h) and gpd (GPD), keep full floating-point precision (1 m³/h = 6,340.1292566 GPD; 1 GPD = 0.000157725 m³/h) during intermediate calculations and round only the final us gallons per day figure to match your instrument tolerance.
