Tips & Best Practices
-
Always confirm the origin of the unit to ensure correct imperial versus US distinctions
-
Use conversions mainly for historical, legal, or pharmaceutical research rather than modern clinical practice
-
Refer to metric units for current and precise medical dosing
-
Cross-check converted values when working with very small liquid volumes due to measurement system differences
Limitations
-
Units originate from historical systems with differing base measures; this can affect precision, especially for small volumes
-
Modern pharmaceutical standards favor metric units over traditional apothecary units
-
Conversions are approximate because of differences between UK and US fluid ounce definitions and rounding
