1. What is GPM to m³/h Conversion?

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

Purpose: It helps engineers, technicians, and professionals 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 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 sizing, and process control in various industries including water treatment, chemical processing, and HVAC.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: How precise is the conversion factor?
A: The factor 4.402 is based on the US gallon (3.78541 liters) and provides precise conversion for most practical applications.

Q3: What's the reverse conversion?
A: To convert m³/h to GPM, multiply by 4.402 (GPM = m³/h × 4.402).

Q4: Does this work for any liquid?
A: Yes, the conversion is based on volume flow rate, not the liquid properties.

Q5: When would I need this conversion?
A: When working with international equipment specifications, comparing system performance data, or when different parts of a system use different units.
