1. What is a kg/hr to GPM Water Calculator?

Definition: This calculator converts water flow rate from kilograms per hour (kg/hr) to gallons per minute (GPM).

Purpose: It helps engineers, plumbers, and technicians convert between metric and imperial flow rate units for water systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Flow rate in gallons per minute (GPM)
• \( W \) — Flow rate in kilograms per hour (kg/hr)
• 3.785 — Liters per gallon conversion factor
• 60 — Minutes per hour conversion

Explanation: Since 1 kg of water equals 1 liter, we convert liters to gallons and hours to minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion ensures proper system design, pump sizing, and compliance with specifications that may use different unit systems.

4. Using the Calculator

Tips: Simply enter the water flow rate in kg/hr. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 3.785 in the formula?
A: 3.785 liters equals 1 gallon, which is needed to convert between metric and imperial volume units.

Q2: Does this work for other liquids?
A: Only for water or liquids with similar density (1 kg/L). For other liquids, you'd need to account for different densities.

Q3: How accurate is this conversion?
A: It's mathematically exact for water at standard conditions (4°C, 1 atm pressure).

Q4: What's a typical kg/hr value for household water?
A: A standard shower might use about 300-600 kg/hr (which converts to 1.3-2.6 GPM).

Q5: Can I convert GPM back to kg/hr?
A: Yes, use the inverse formula: W = Q × 3.785 × 60
