1. What is GPM to m³/h Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The conversion factor 4.402 comes from the relationship between gallons and cubic meters, and minutes to hours.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump selection, and process control in various industries.

4. Using the Calculator

Tips: Simply enter the flow rate in US gallons per minute (GPM). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the exact conversion factor?
A: 1 US GPM = 0.227124 m³/h, or equivalently 1 m³/h = 4.40287 US GPM.

Q2: Does this work for imperial gallons?
A: No, this is specifically for US gallons. Imperial gallons would use a different conversion factor.

Q3: When would I need this conversion?
A: When working with international specifications, pump curves, or comparing systems using different unit systems.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact, assuming proper unit definitions are used.

Q5: Can I convert m³/h back to GPM?
A: Yes, simply multiply m³/h by 4.402 to get US GPM.
