What Is This Tool?
This converter transforms flow measurements from ounce (UK) per hour, a mass flow unit used for very low throughput, into gallon (UK) per minute, a volumetric flow unit commonly used in plumbing and engineering in imperial units.
How to Use This Tool?
-
Enter the flow value in ounce (UK) per hour
-
Select ounce (UK)/hour as the 'from' unit
-
Choose gallon (UK)/minute as the 'to' unit
-
Click convert to see the equivalent flow rate in gallon (UK)/minute
Key Features
-
Converts low-rate mass flow to volumetric flow in imperial units
-
Useful for pharmaceuticals, chemical dosing, and plumbing applications
-
Browser-based and easy to use without complex inputs
-
Displays conversion based on a fixed rate for quick reference
Examples
-
Convert 10 oz (UK)/h: 10 × 0.0001041667 = 0.001041667 gallon (UK)/minute
-
Convert 50 oz (UK)/h: 50 × 0.0001041667 = 0.005208335 gallon (UK)/minute
Common Use Cases
-
Dosing small quantities of laboratory reagents or chemicals with precision pumps
-
Calibrating or specifying metering devices in pharmaceutical or specialty manufacturing
-
Micro-dosing ingredients in perfumery and flavoring processes
-
Sizing pumps and pipes for water supply and firefighting where imperial gallons apply
-
Documenting flow rates in industrial or legacy systems using UK units
Tips & Best Practices
-
Always ensure consistent unit use between mass and volumetric flow rates
-
Consider density information when converting between mass flow and volumetric flow for accuracy
-
Use this conversion primarily for low-rate flows and micro-dosing scenarios
-
Apply standard imperial unit flow rates when specifying pumps and plumbing equipment
Limitations
-
Measures different physical quantities: mass flow versus volumetric flow
-
Conversion assumes constant density or requires density data for exact calculation
-
Less suited for high-volume fluid dynamics due to very small ounce (UK)/hour values
Frequently Asked Questions
-
Why is this conversion important in pharmaceuticals?
-
It helps translate very low mass flow dosing rates into volumetric rates compatible with pump and plumbing equipment.
-
Can I use this converter for high-volume flow rates?
-
No, it is designed for very low flow rates and micro-dosing, not for high-volume fluid dynamics.
-
Does this conversion require knowing fluid density?
-
Yes, because it converts between mass and volumetric flow, having density information improves accuracy.
Key Terminology
-
Ounce (UK)/hour [oz (UK)/h]
-
A mass flow rate indicating one UK avoirdupois ounce passing per hour, used for expressing very low mass throughput.
-
Gallon (UK)/minute
-
A volumetric flow rate representing the number of UK gallons flowing per minute, commonly used in imperial measurement systems.
-
Mass Flow Rate
-
The amount of mass passing through a point per unit time.
-
Volumetric Flow Rate
-
The volume of fluid moving through a point per unit time.
