What Is This Tool?
This tool converts volumetric flow rates from gallon (UK)/hour, an imperial unit for small-scale flows, to acre-foot/day, a larger-scale unit often used in water-resources and hydraulic engineering.
How to Use This Tool?
-
Enter the flow value in gallon (UK)/hour units
-
Select gallon (UK)/hour as the input unit and acre-foot/day as the output unit
-
Click the convert button to see the result in acre-foot/day
-
Use the result for planning or reporting water volumes in larger-scale systems
Key Features
-
Converts flow rates between gallon (UK)/hour and acre-foot/day units
-
Based on precise conversion rate: 1 gal (UK)/h = 0.0000884534 ac*ft/d
-
Supports applications in irrigation, water treatment, and resource management
-
Includes example calculations for quick reference
-
Browser-based, easy to use without installation
Examples
-
10 gal (UK)/h converts to 0.000884534 ac*ft/d
-
100 gal (UK)/h converts to 0.00884534 ac*ft/d
Common Use Cases
-
Specifying low-volume pump or chemical dosing rates in UK water treatment operations
-
Expressing drip irrigation or condensate flow rates in agricultural systems
-
Reporting reservoir or river inflows in hydraulic engineering projects
-
Accounting for municipal or industrial surface water withdrawals
-
Converting small-scale imperial flow measurements to large-scale water resource units for management
Tips & Best Practices
-
Ensure flow values are in imperial UK gallons per hour for accurate conversion
-
Be mindful that converted acre-foot/day values can be very small for low flows
-
Use appropriate significant figures to maintain precision in sensitive calculations
-
Double-check unit definitions due to differences between UK and US gallons
-
Leverage the tool for consistent reporting across water resource applications
Limitations
-
Converting small flows may result in values close to zero in acre-foot/day
-
Precision and rounding differences can affect highly sensitive calculations
-
Must ensure to use the UK gallon definition, as it differs from the US gallon
-
The units represent vastly different scales, so interpret results accordingly
Frequently Asked Questions
-
What is a gallon (UK)/hour?
-
It is a volumetric flow rate equal to one United Kingdom (imperial) gallon of fluid per hour, where one UK gallon equals 4.54609 liters.
-
What does acre-foot/day measure?
-
Acre-foot per day measures the volume of water delivered or removed over one day across an area of one acre to a depth of one foot, commonly used in water management.
-
Why convert from gallon (UK)/hour to acre-foot/day?
-
Converting these units helps relate small-scale flow rates measured in imperial gallons per hour to larger water resource volumes standardized in acre-feet per day for planning and reporting.
Key Terminology
-
Gallon (UK)/hour [gal (UK)/h]
-
A flow rate unit representing one UK (imperial) gallon of fluid flowing per hour; 1 gal (UK) equals 4.54609 liters.
-
Acre-foot/day [ac*ft/d]
-
A volumetric flow rate equal to one acre-foot of water delivered each day, used in agricultural and water resource contexts.
-
Volumetric Flow Rate
-
The measure of volume of fluid passing through a point per unit of time.
