What Is This Tool?
This converter transforms flow measurements from ounce (UK) per hour, a mass flow rate, into milliliter per day, a volumetric flow rate. It is designed for applications involving very low rates of fluid or chemical transfer, ensuring convenient unit translation for precision dosing, clinical monitoring, and laboratory analysis.
How to Use This Tool?
-
Enter the value in ounce (UK)/hour that you want to convert

Tips & Best Practices
-
Ensure consistent fluid density for accurate mass-to-volume conversions
-
Apply the tool when flows are steady to avoid measurement inaccuracies
-
Use the converted values to correlate dosing precision in both mass and volume terms
-
Consider fluid properties when interpreting conversion results across different substances
Limitations
-
Accuracy depends on assuming constant fluid density or specific gravity
-
Not suitable for fluctuating or unsteady flow conditions
-
Variation in fluid viscosity or density can affect conversion accuracy
Frequently Asked Questions
-
Why does the conversion depend on fluid density?
-
Because the tool converts a mass flow rate (oz (UK)/h) into a volume flow rate (mL/d), fluid density or specific gravity affects how mass relates to volume.
-
Can this tool be used for high flow rates?
-
This converter is optimized for very low flow rates; for high flow rates, other conversion methods might be more appropriate.
-
Is this conversion accurate for all fluids?
-
The conversion assumes steady flow and constant fluid properties; varying densities or viscosities can impact accuracy.
Key Terminology
-
Ounce (UK)/hour [oz (UK)/h]
-
A mass flow rate metric representing the passage of one UK avoirdupois ounce per hour, used for very low mass throughput.
-
Milliliter/day [mL/d]
-
A volumetric flow rate unit indicating the volume of one milliliter moved or consumed over a day, suitable for very low continuous flow rates.
-
Mass Flow Rate
-
The measurement of mass passing through a point per unit time.
-
Volumetric Flow Rate
-
The measurement of volume passing through a point per unit time.
