1. What is a m3/h to GPM Converter?

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 Converter Work?

The converter 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 (1 m³ = 264.172 gallons) and time (1 hour = 60 minutes) conversions.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential when working with international specifications, equipment from different regions, or when documentation uses mixed units.

4. Using the Converter

Tips: Simply enter the flow rate in m³/h and the converter will automatically calculate the equivalent in GPM. The value must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: What's a typical flow rate in m3/h for residential water systems?
A: Typically 0.5-2 m³/h (2.2-8.8 GPM) for household water supply.

Q3: Can I convert GPM back to m3/h?
A: Yes, divide GPM by 4.402 or use our GPM to m3/h converter tool.

Q4: Does this work for any liquid?
A: Yes, as long as you're measuring volumetric flow rate (not mass flow rate).

Q5: How precise is this conversion?
A: The 4.402 factor provides precision to 3 decimal places, sufficient for most engineering applications.
