m³/h to GPM Calculator
Flow rate conversions are essential in plumbing, HVAC, irrigation, and engineering projects. m³/h (cubic meters per hour) measures volume flow in metric units, while GPM (gallons per minute) is commonly used in the US. Accurate conversion ensures correct pump sizing, pipe selection, and flow analysis.
Why Flow Rate Conversion Matters
Different industries use different units for measuring liquid flow. HVAC engineers work with m³/h, while US plumbers prefer GPM. Using the wrong units can lead to incorrect pump specifications and system failures.
Formula Used in This Calculator
The calculator applies the standard conversion formula:
For reverse calculation: m³/h = GPM ÷ 4.40288
Example Calculation Table
| Flow (m³/h) | Flow (GPM) | Application |
|---|---|---|
| 10 | 44.03 | Small pump |
| 25 | 110.07 | Medium pump |
| 50 | 220.14 | Industrial application |
*Values rounded to two decimal places for readability.
