Gallons per Day (GPD) to Liters per Minute (L/min) Flow Unit Conversion Calculator

This tool helps users convert Gallons per Day (GPD) to Liters per Minute (L/min), supporting professionals in water treatment, filtration systems, and fluid dosing operations where converting long-duration U.S. customary units into real-time metric flow is essential.

Definition: Gallons per Day (GPD)

Commonly used in the U.S. for low-flow applications such water filtration, irrigation, and dosing systems, Gallons per Day (GPD) is a unit of volume flow measuring the total volume of fluid moved or processed in a 24-hour period.

Key Applications of Gallons per Day (GPD):

• Reverse Osmosis Systems: Rates membrane capacity and permeate flow rates.
• Water Filtration Units: Indicates commercial and household filter throughput.
• Chemical Dosing Pumps: Calculates daily cycle chemical delivery.
• Irrigation Systems: Irrigation systems control ongoing and gradual watering activities.

Definition: Liters per Minute (L/min)

A metric quantity called liters per minute (L/min) indicates the volume of fluid moved every minute. It is often used in real-time flow monitoring, dosing systems, and industrial applications requiring continuous flow measurement.

Key Applications of Liters per Minute (L/min):

• Plumbing and Piping Systems: Tracks appliance and fixture water flow.
• Medical Equipment: Used in oxygen concentrators and IV delivery systems.
• Process Automation: Monitors mixing and dosing in real-time.
• Industrial Machinery: Measures flow in transfer, lubrication, and cooling systems.

Formula for GPD to L/min Conversion

This formula will help you to convert Gallons per Day (GPD) to Liters per Minute (L/min):

Flow (L/min)=Flow (GPD)×0.002630

1 U.S. gallon = 3.78541 liters and 1 day = 1,440 minutes,
so:
GPD × 3.78541 ÷ 1,440 = GPD × 0.002630 L/min

Example Calculation

Convert 5,000 GPD to L/min:

5,000×0.002630=13.15 L/min

Thus, 13.15 Liters per Minute is the equivalent to 5,000 GPD.
