About This Calculator
This calculator converts between gallons per minute (GPM) and cubic meters per hour (m³/h). It's useful in industrial, water supply, and process control systems where metric-imperial unit consistency is required.
How It Works
- Select the direction: GPM to m³/h or m³/h to GPM.
- Enter the flow value.
- The result is calculated using:
m³/h =
GPM × 3.7854160
GPM =
m³/h × 603.78541
Note: 1 GPM ≈ 0.227124 m³/h based on US gallons.
