1. What is GPM to m³/s Conversion?

The GPM to m³/s conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic meters per second (m³/s). This conversion is essential in engineering, hydraulics, and fluid dynamics where different unit systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 6.30901964 \times 10^{-5} \) — Conversion factor from GPM to m³/s

Explanation: One gallon per minute equals approximately 0.00006309 cubic meters per second. The conversion factor is derived from the relationship between US gallons and cubic meters.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, hydraulic system design, water treatment plants, and scientific research where metric units are standard.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 6.30901964 × 10⁻⁵ m³/s per GPM, based on the US gallon definition (1 gallon = 0.00378541 cubic meters).

Q2: Is this conversion for US gallons or imperial gallons?
A: This conversion uses US gallons. Imperial gallons have a different conversion factor (approximately 5.946 × 10⁻⁵ m³/s per imperial GPM).

Q3: When is this conversion typically used?
A: Commonly used in water supply systems, HVAC design, chemical processing, and any application involving fluid flow measurements between imperial and metric systems.

Q4: How accurate is this conversion?
A: The conversion is highly accurate for most engineering purposes, with the factor precise to 9 significant figures.

Q5: Can I convert back from m³/s to GPM?
A: Yes, to convert back, divide the m³/s value by 6.30901964 × 10⁻⁵ or multiply by approximately 15,850.32.
