1. What is m³/h 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, plumbers, and technicians work with flow rates in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
• \( Q_{m3h} \) — Flow rate in cubic meters per hour (m³/h)

Explanation: The conversion factor 4.402 comes from the relationship between cubic meters and gallons (1 m³ = 264.172 gallons) and between hours and minutes (1 hour = 60 minutes).

3. Importance of Flow Rate Conversion

Details: Proper unit conversion ensures accurate system design, pump selection, and process control in fluid systems.

4. Using the Calculator

Tips: Enter the flow rate in m³/h. The calculator will automatically provide the equivalent in GPM.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between m³/h and GPM?
A: Different industries and countries use different units, and conversion is often needed for equipment specifications and international projects.

Q2: How accurate is the conversion factor?
A: The factor 4.402867 is precise, though results are typically rounded to 3 decimal places for practical applications.

Q3: Can I convert GPM back to m³/h?
A: Yes, divide GPM by 4.402 to get m³/h.

Q4: What's a typical flow rate in m³/h for household water?
A: A standard faucet might flow about 0.5-1 m³/h (2.2-4.4 GPM).

Q5: Does this work for any liquid?
A: Yes, the conversion is based on volume flow rate, independent of the liquid type.
