Why do we convert cubic foot/minute to gallon (US)/second?

To express air flow volumes in terms of liquid volumetric rates, enabling comparisons and calculations in areas like fluid handling and pumping.

What is the conversion formula between these units?

Multiply the flow rate in cubic foot per minute by 0.1246753247 to get the value in gallon (US) per second.

Can this converter be used for any fluid?

It is primarily designed for typical air flow for cubic foot/minute and liquid flow for gallon (US)/second; variations in fluid density are not considered.

What should I be careful about when using this conversion?

Ensure you understand the difference in fluid types and that timing units differ—one per minute versus one per second.

What Is This Tool?

This tool enables conversion of flow rates from cubic foot per minute, a common volumetric air flow unit, to gallon (US) per second, a volumetric liquid flow rate measure. It supports accurate expression of flow data for fluid handling applications.

How to Use This Tool?

Enter the value in cubic foot per minute representing the flow rate to convert.
Select cubic foot/minute as the input unit and gallon (US)/second as the output unit.
Click convert to see the equivalent flow rate expressed in gallon (US)/second.
Use results to support fluid flow analyses in ventilation, water pumping, or liquid transfer.

Key Features

Converts airflow volume rates (cubic foot/minute) into liquid flow rates (gallon (US)/second).
Includes practical conversion formula and rate for straightforward calculations.
Applicable for engineering contexts like HVAC, irrigation, and industrial plumbing.
Browser-based and simple to use with direct input and output units.

Examples

5 cubic foot/minute equals 0.6233766235 gallon (US)/second after conversion.
10 cubic foot/minute equals 1.246753247 gallon (US)/second.
Apply the formula: multiply cubic foot/minute values by 0.1246753247 to get gallons (US)/second.

Common Use Cases

Defining fan or blower airflow capacity and room ventilation levels in HVAC systems.
Evaluating discharge rates for high-capacity firefighting and water pumps.
Measuring flow in irrigation valves and large industrial water plumbing lines.
Estimating short-duration flow for tanker unloading and liquid transfer operations.

Tips & Best Practices

Always ensure time units are consistent since cubic foot/minute and gallon (US)/second represent different time scales.
Understand the fluid type difference when converting air volume rates to liquid flow measurements.
Use the precise conversion rate 0.1246753247 for accurate volumetric rate conversion.
Verify application context especially if fluid density or viscosity varies significantly.

Limitations

Conversion assumes volumetric equivalence but does not factor in fluid density differences between air and liquids.
Precision depends on correctly accounting for the differing time units—minutes versus seconds.
Not suitable for flows involving compressible fluids without additional adjustments.

Key Terminology

Cubic foot/minute [ft^3/min]: A volumetric flow unit measuring the volume of air passing a reference area each minute, often used in HVAC and pneumatic systems.
Gallon (US)/second: A volumetric flow unit equaling one U.S. liquid gallon passing a point every second, used in water pumping, irrigation, and liquid transfer.
Volumetric Flow Rate: The volume of fluid passing through a cross-section per unit of time.

Quick Knowledge Check

What does 1 cubic foot/minute measure?

A liquid volume flow per second

An air volume flowing per minute through a cross-section

A solid volume per hour

What is the unit equivalent to 1 gallon (US)/second?

3.785411784 liters per second

0.1 cubic meter per hour

1 gallon per minute

Why must timing units be carefully considered in conversions?

Because cubic foot/minute and gallon/second use different time intervals

Because both units measure weight, not volume

Because timing units do not affect volumetric flow
