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, plumbers, and professionals working with fluid systems across different measurement standards.

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
• \( 15850.323141488903 \) — Exact conversion factor

Explanation: This conversion factor accounts for the volume difference between cubic meters and gallons, and the time conversion from seconds to minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international projects, equipment specification, hydraulic calculations, and ensuring compatibility between systems using different measurement units.

4. Using the Converter

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor so precise?
A: The factor 15850.323141488903 is exact based on the definition of 1 US gallon = 0.003785411784 cubic meters and 60 seconds per minute.

Q2: What are typical flow rates in m³/s and GPM?
A: Household faucet: 0.000063 m³/s (1 GPM), Garden hose: 0.000315 m³/s (5 GPM), Fire hydrant: 0.00126 m³/s (20 GPM).

Q3: Is this for US gallons or imperial gallons?
