1. What is a Flow Rate Conversion Calculator?

Definition: This calculator converts between different flow rate units including gallons per minute (GPM), liters per minute (LPM), and cubic feet per second (CFS).

Purpose: It helps engineers, plumbers, and technicians work with flow rate measurements in different unit systems.

2. How Does the Calculator Work?

The calculator uses these conversion formulas:

\[ Q_{gpm} = \frac{Q_{lpm}}{3.785} \] \[ Q_{gpm} = Q_{cfs} \times 448.83 \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute
\( Q_{lpm} \) — Flow rate in liters per minute
\( Q_{cfs} \) — Flow rate in cubic feet per second

Explanation: Enter any one value and the calculator automatically computes the equivalent values in other units.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump sizing, and comparing specifications from different regions that use different measurement units.

4. Using the Calculator

Tips: Enter any one flow rate value (GPM, LPM, or CFS) and the calculator will automatically compute the other two. Only one field needs to be filled.

5. Frequently Asked Questions (FAQ)

Q1: Why are there different flow rate units?
A: Different industries and countries use different measurement systems (imperial vs metric).

Q2: What's the conversion between GPM and LPM?
A: 1 GPM = 3.785 LPM, and 1 LPM = 0.264 GPM.

Q3: How many GPM are in 1 CFS?
A: 1 cubic foot per second equals 448.83 gallons per minute.

Q4: Which unit should I use?
A: GPM is common in US plumbing, LPM in metric countries, CFS in large-scale water systems.

Q5: Are these conversions exact?
A: Yes, these are exact unit conversions based on standard definitions.
