Convert Between m³/h and GPM

About This Calculator

This calculator converts flow rate between cubic meters per hour (m³/h) and gallons per minute (GPM). It is ideal for fluid system design, pump sizing, and international engineering projects.

How It Works

  1. Select the conversion direction: m³/h to GPM or GPM to m³/h.
  2. Enter the flow value in the selected unit.
  3. The result is calculated using these formulas:
GPM = m³/h × 4.40287
m³/h = GPM ÷ 4.40287
Note: 1 m³/h ≈ 4.40287 GPM. The value is derived from converting cubic meters to US gallons and hours to minutes.
