1. What is m3/hr to GPM Conversion?

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

Purpose: It helps engineers, technicians, and professionals 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 unit conversion is crucial when working with international standards, equipment specifications, or when comparing system performance data.

4. Using the Calculator

Tips: Simply enter the flow rate in m³/h and the calculator will instantly provide the equivalent in GPM. The input must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 4.402?
A: It combines volume conversion (1 m³ = 264.172 gallons) and time conversion (1 hour = 60 minutes): 264.172/60 ≈ 4.402.

Q2: When would I need this conversion?
A: When working with pumps, pipes, or fluid systems that use different measurement standards (metric vs imperial).

Q3: Is this conversion exact?
A: Yes, the conversion factor is mathematically precise, though actual flow rates may vary slightly due to measurement tolerances.

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

Q5: Does this work for any liquid?
A: Yes, as it's a volumetric flow conversion. For mass flow rates, you'd need to consider fluid density.
