1. What is Cubic Meter Per Hour To GPM Conversion?

The cubic meter per hour to gallons per minute conversion is used to convert volumetric flow rate measurements between metric and imperial units. This conversion is essential in various engineering, industrial, and fluid dynamics applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Gallons per minute
• \( m³/h \) — Cubic meters per hour
• \( 4.4029 \) — Conversion factor

Explanation: The conversion factor 4.4029 represents the number of US gallons in one cubic meter (264.172) divided by 60 minutes per hour.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, pump sizing, pipeline design, and fluid system calculations where different measurement systems are used.

4. Using the Calculator

Tips: Enter the flow rate in cubic meters per hour. The value must be non-negative. The calculator will automatically convert to gallons per minute with high precision.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 4.402867543, which is often rounded to 4.4029 for practical calculations.

Q2: Are these US gallons or imperial gallons?
A: This conversion uses US gallons (1 US gallon = 3.78541 liters). Imperial gallons are larger (1 imperial gallon = 4.54609 liters).

Q3: Where is this conversion commonly used?
A: Commonly used in water treatment plants, HVAC systems, irrigation design, and any application involving fluid flow measurements.

Q4: How accurate is this conversion?
