| From: | To: |
GPM (gallons per minute) to m³/s (cubic meters per second) conversion is used to convert flow rate measurements between imperial and metric systems. This is particularly important in engineering, hydraulics, and fluid dynamics applications where international standards may require metric units.
The calculator uses the conversion formula:
Where:
Explanation: One gallon per minute equals approximately 0.00006309 cubic meters per second based on the standard conversion between US gallons and cubic meters.
Details: Accurate flow rate conversion is crucial for international engineering projects, hydraulic system design, pump specifications, and compliance with metric system standards used in most countries outside the United States.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be a positive number. The calculator will automatically compute the equivalent flow rate in cubic meters per second (m³/s).
Q1: Why is the conversion factor 0.00006309?
A: This factor is derived from the relationship between gallons and cubic meters (1 gallon = 0.00378541 m³) divided by 60 seconds in a minute.
Q2: Is this conversion using US gallons or imperial gallons?
A: This calculator uses US gallons. Imperial gallons (used in the UK) have a different conversion factor of approximately 0.00007577.
Q3: What are typical flow rates in GPM and m³/s?
A: Household faucets: 1-2 GPM (0.000063-0.000126 m³/s), Showerheads: 2.5 GPM (0.000158 m³/s), Fire hoses: 250+ GPM (0.0158+ m³/s).
Q4: When would I need to convert GPM to m³/s?
A: Common applications include international engineering projects, scientific research, hydraulic system design, and when working with equipment specifications from different countries.
Q5: Can I convert m³/s back to GPM?
A: Yes, the reverse conversion is: GPM = m³/s ÷ 0.00006309 or GPM = m³/s × 15,850.32.
