1. What is Flow Rate Conversion?

Flow rate conversion between cubic meters per second (m³/s) and gallons per minute (GPM) is essential for engineers, hydrologists, and professionals working with fluid systems. This conversion allows for seamless transition between metric and imperial units in various applications.

2. How Does the Converter Work?

The converter uses the precise conversion formula:

Where:

• \( m³/s \) — Flow rate in cubic meters per second
• \( GPM \) — Flow rate in gallons per minute
• \( 15850.323141488903 \) — Conversion factor

Explanation: One cubic meter equals 264.172 gallons, and one minute contains 60 seconds, resulting in the conversion factor of 264.172 × 60 = 15850.32.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, water resource management, pump sizing, pipeline design, and industrial process control where both metric and imperial units are used.

4. Using the Converter

Tips: Enter the flow rate in cubic meters per second (m³/s). The value must be non-negative. The converter will instantly calculate the equivalent flow rate in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: What is the conversion factor from m³/s to GPM?
A: The precise conversion factor is 15850.323141488903 GPM per m³/s.

Q2: Why is this conversion important in engineering?
A: Many international projects require conversion between metric (m³/s) and imperial (GPM) units for pump specifications, pipe sizing, and flow measurement.

Q3: What are typical flow rates in m³/s and GPM?
A: Household water supply: 0.0001-0.001 m³/s (1.5-15 GPM), Small river: 1-10 m³/s (15,000-150,000 GPM), Large pump: 0.1-1 m³/s (1,500-15,000 GPM).

Q4: How accurate is this conversion?
A: The conversion uses the standard definition where 1 cubic meter = 264.172 gallons, providing high precision suitable for engineering applications.

Q5: Can I convert GPM back to m³/s?
A: Yes, use the inverse formula: m³/s = GPM ÷ 15850.323141488903.
