Flow Rate Converter

Convert between different units of fluid flow rate like L/s and GPM.

Understanding the Converter

Flow rate measures the volume of fluid that passes through a surface per unit time. This tool is crucial for engineers, plumbers, and scientists working with fluid dynamics.

All conversions use cubic meters per second (m³/s), the SI unit, as a base reference to ensure accuracy.

Formula Used

Standardized Conversion Process

To ensure accuracy, all conversions use the cubic meter per second (m³/s) as a common base unit.

  1. Convert to m³/s: The input value is converted to m³/s by multiplying it by its conversion factor.
  2. Convert to Target Unit: The m³/s value is then converted to the desired final unit by dividing it by the target unit's conversion factor.

Common Flow Rate Units

UnitAbbreviationDefinition & Context
Cubic Meter per Secondm³/sThe SI derived unit. Used for large-scale flows like rivers.
Liter per SecondL/sA common metric unit for smaller-scale flows. 1 m³/s = 1000 L/s.
US Gallons per MinuteGPMStandard unit in the US for pumps, showerheads, and plumbing.
Imperial Gallons per MinuteGPMUsed in the UK and some other countries. An Imperial gallon is ~20% larger than a US gallon.
Cubic Feet per MinuteCFMCommonly used in the US for airflow in HVAC systems and for gas flow.

Frequently Asked Questions

What does GPM mean?

GPM stands for Gallons Per Minute. It's a critical measurement for plumbing and irrigation, indicating how many gallons of water flow past a point in one minute. It's important to specify whether you mean US or Imperial gallons.

What does CFM mean?

CFM stands for Cubic Feet per Minute. It's a measurement of the volume of air or gas that moves in a minute. It's essential for sizing fans, air conditioners, and ventilation systems.

How is flow rate related to velocity?

Flow rate is the volume of fluid passing a point per unit time (e.g., m³/s), while velocity is the speed of the fluid at that point (e.g., m/s). They are related by the equation: Flow Rate = Area × Velocity, where Area is the cross-sectional area of the pipe or channel.

Why are there different gallons?

The US and Imperial systems evolved separately. The US gallon was based on an older English wine gallon, while the Imperial gallon was defined later. The Imperial gallon is about 20% larger than the US gallon.

Summary

The Flow Rate Converter is an essential tool for engineers, HVAC technicians, plumbers, and anyone working with fluid systems. It simplifies conversions between metric and imperial units of fluid flow.
