GPM to LPM Conversion Formula

The equation for converting GPM to LPM is:

LPM = GPM × 3.78541

Converting 12 GPM to LPM

• Given flow rate = 12 GPM
• Calculation: 12 × 3.78541
• Result: 45.42 LPM

How to Convert Gallons Per Minute to Liters Per Minute?

Take a water heater rated at 20 GPM:

• Identify initial flow rate: 20 GPM
• Apply conversion factor: 20 × 3.78541
• Calculate final value: 75.71 LPM

What is GPM and LPM?

GPM stands for Gallons Per Minute, which is a unit of measurement used to quantify the flow rate of liquids, particularly water. It indicates how many gallons of liquid pass through a specific point in a system within one minute.

The formula for calculating GPM is:

GPM = Flow (in gallons) / Time (in minutes)

LPM stands for Liters Per Minute, which measures the flow rate of liquids in liters per minute. Similar to GPM, LPM is used to describe how much liquid a pump can move in one minute.

The calculation for LPM follows the same principle as GPM but uses liters instead of gallons. The formula can be expressed as:

LPM = Flow (in liters) / Time (in minutes)
