1. What is GPH (Gallons Per Hour)?

Definition: GPH measures the volumetric flow rate of liquids in gallons per hour.

Purpose: This calculator converts flow rate from cubic meters per second (m³/s) to gallons per hour (gal/h).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{GPH} \) — Gallons per hour
• \( Q \) — Flow rate in cubic meters per second (m³/s)
• \( 3600 \) — Seconds to hours conversion
• \( 0.003785 \) — Cubic meters to gallons conversion

Explanation: The formula converts the flow rate from m³/s to gal/h by accounting for both time and volume unit conversions.

3. Importance of GPH Calculation

Details: GPH measurements are crucial in fluid systems, irrigation, fuel consumption, and industrial processes where flow rates need to be monitored or controlled.

4. Using the Calculator

Tips: Enter the flow rate in cubic meters per second (m³/s). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert from m³/s to GPH?
A: Many industries use different units - m³/s is standard in physics while GPH is common in practical applications.

Q2: What's the conversion factor breakdown?
A: 1 m³ = 264.172 gallons (≈1/0.003785) and 1 hour = 3600 seconds.

Q3: Can I use this for any liquid?
A: Yes, the calculation is volumetric and independent of liquid type (though viscosity affects actual flow).

Q4: How accurate is this conversion?
A: The mathematical conversion is exact, but real-world measurements may have instrument errors.

Q5: What's a typical GPH range for household water?
A: Standard faucets flow about 1-2 GPM (60-120 GPH), while showers are typically 2.5 GPM (150 GPH).
