1. What is m3/h to GPM Calculator?

Definition: This calculator converts flow rate from cubic meters per hour (m³/h) to gallons per minute (GPM).

Purpose: It helps engineers, plumbers, and technicians working with fluid systems to convert between metric and imperial flow rate units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{gpm} = Q_{m3h} \times 4.402 \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
\( Q_{m3h} \) — Flow rate in cubic meters per hour (m³/h)
4.402 — Conversion factor (1 m³/h = 4.402 GPM)

Explanation: The conversion factor accounts for both volume conversion (1 m³ = 264.172 gallons) and time conversion (1 hour = 60 minutes).

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump selection, and ensuring compatibility between components using different measurement systems.

4. Using the Calculator

Tips: Simply enter the flow rate in cubic meters per hour (m³/h) and the calculator will automatically provide the equivalent in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 4.402?
A: It combines both volume and time conversions: 264.172 gallons/m³ ÷ 60 minutes/hour = 4.402867.

Q2: How accurate is this conversion?
A: The conversion is mathematically exact, though practical measurements may have instrumentation errors.

Q3: When would I need this conversion?
A: When working with international equipment specifications, comparing pump performance curves, or designing systems with mixed units.

Q4: Can I convert GPM back to m³/h?
A: Yes, divide GPM by 4.402 to get m³/h, or use our GPM to m³/h calculator.

Q5: Does this work for all liquids?
A: Yes, the conversion is based on volume flow rate and is independent of liquid density.
