What Is This Tool?
This converter transforms flow measurements from ounce (UK) per hour, a unit expressing very low mass flow rates, into gallon (US) per minute, a volume flow rate commonly used in plumbing and automotive contexts. It supports users needing precise unit translation between mass and volumetric flow rates.

-
100 oz (UK)/h equals 0.0125099 gallon (US)/minute when converted
-
These examples demonstrate converting very low mass flow rates into volumetric flow units
Common Use Cases
-
Low-rate dosing of chemicals and reagents with precision pumps in laboratories
-
Calibration of drip-feed devices in pharmaceutical manufacturing
-
Micro-dosing in perfumery or flavoring applications involving small ingredient masses
-
Design and maintenance of residential and commercial plumbing systems
-
Measuring water flow in HVAC and cooling tower systems
-
Monitoring fuel or liquid transfer rates in automotive and small-engine environments
Tips & Best Practices
-
Remember that ounce (UK)/hour measures mass flow, so conversions to volume may require fluid density information
-
Use this conversion for approximate translation where precise density data is unavailable
-
Double-check units and input values before converting to avoid errors
-
Apply conversion outputs in contexts where volumetric flow rates are standard, such as plumbing or fuel monitoring
-
Consult fluid properties to improve accuracy when necessary
Limitations
-
The conversion assumes a mass-to-volume relationship that depends on fluid density, which varies by substance
-
Ounce (UK)/hour is a mass flow rate, while gallon (US)/minute is volumetric; exact conversion requires density knowledge
-
Very small mass flow rates correspond to extremely low volumes per minute, which can challenge measurement in some devices
-
Users should consider these factors when applying the conversion in practical scenarios
Frequently Asked Questions
-
What does ounce (UK)/hour measure?
-
It measures the mass flow rate of one UK avoirdupois ounce passing per hour, often used for very low mass throughput.
-
What is gallon (US)/minute used for?
-
It is a volumetric flow rate unit representing the number of US liquid gallons flowing past a point each minute, common in plumbing and fuel measurement.
-
Do I need fluid density to convert accurately between these units?
-
Yes, because ounce (UK)/hour measures mass flow and gallon (US)/minute measures volume flow, fluid density affects accuracy.
Key Terminology
-
Ounce (UK)/hour [oz (UK)/h]
-

-
Gallon (US)/minute (gpm)
-
A volumetric flow rate unit indicating the number of US liquid gallons passing a point each minute.
-
Mass flow rate
-
The amount of mass passing through a given area per unit time.
-
Volumetric flow rate
-
The volume of fluid passing through a given area per unit time.
-
Conversion factor
-
A numerical value used to convert one unit of measurement to another.
