Volume ≠ weight
One of the most common measurement mistakes is treating fluid ounces (fl oz) and weight ounces (oz) as interchangeable. They’re not.
- Fluid ounce (fl oz): a unit of volume — how much space a liquid occupies.
- Ounce (oz): a unit of weight — how heavy something is.
Why this matters for pint conversions
Pint conversions only apply to fluid ounces. If a recipe says “8 oz of flour,” that’s weight — converting it to pints makes no sense.
