What Is This Tool?
This tool allows you to convert flow measurements from gallon (UK)/minute, which measures the volume of fluid delivered each minute using imperial gallons, to cubic foot/minute [ft³/min], a unit measuring volumetric air flow in cubic feet per minute used widely in ventilation and HVAC systems.
How to Use This Tool?
-
Enter the flow rate value in gallon (UK)/minute
-
Select gallon (UK)/minute as the input unit and cubic foot/minute as the output unit
-
Click convert to see the equivalent flow rate in cubic foot/minute [ft³/min]
-
Use the results to assist with pump sizing, ventilation design, or flow control equipment
Key Features
-
Convert between gallon (UK)/minute and cubic foot/minute with a clear and accurate formula
-
Supports volumetric flow rate conversions for engineering and industrial contexts
-
Useful for plumbing, irrigation, firefighting, HVAC, and pneumatic system measurements
-
Browser-based and easy to use with step-by-step instructions
Examples
-
5 gallon (UK)/minute = 0.802718266 cubic foot/minute
-
10 gallon (UK)/minute = 1.605436532 cubic foot/minute
Common Use Cases
-
Specifying capacities for pumps and hoses in water supply, irrigation, or firefighting using imperial units
-
Sizings and rating plumbing fixtures for domestic or commercial water systems
-
Measuring flow rates in industrial documentation or legacy equipment using UK/imperial units
-
Determining fan and blower capacities or ventilation rates in HVAC applications
-
Sizing ductwork and ventilation systems in industrial or smoke control setups
-
Assessing compressed air delivery for pneumatic tools and compressors
Tips & Best Practices
-
Verify that your input values represent volumetric flow rates in UK imperial gallons per minute
-
Use this conversion when integrating fluid flow data with ventilation or pneumatic system measurements
-
Be aware this conversion does not consider changes in fluid properties like density or temperature
-
Ensure you differentiate between UK gallons and US gallons, as conversion rates differ
-
Apply the result to aid engineering decisions in plumbing, HVAC, and industrial design
Limitations
-
Assumes standard fluid properties without adjustments for density or temperature changes
-
Applies only to UK (imperial) gallons, not US liquid gallons
-
Volumetric flow rates may not be equivalent when comparing fluids of different phases or compressibility
Frequently Asked Questions
-
What does gallon (UK)/minute measure?
-
It measures the volumetric flow rate as the number of UK imperial gallons passing a point each minute, commonly used in engineering and plumbing for fluid volume flow.
-
Why convert gallon (UK)/minute to cubic foot/minute?
-
This conversion translates liquid flow measurements from imperial units to cubic volumetric measures used in air flow, ventilation, and pneumatic contexts.
-
Can I use this conversion for US gallons?
-
No, this converter is specific to UK (imperial) gallons; US liquid gallons require a different conversion factor.
Key Terminology
-
Gallon (UK)/minute
-
A volumetric flow rate unit indicating the number of UK imperial gallons flowing each minute, used in fluid volume measurements.
-
Cubic foot/minute [ft³/min]
-
A unit of volumetric flow rate representing one cubic foot of fluid passing a cross-section every minute, commonly used in air flow and ventilation.
-
Volumetric Flow Rate
-
The volume of fluid that passes through a given surface per unit time, expressed in units like gallons per minute or cubic feet per minute.
