This conversion works for fluid ounces, which measure volume, and should not be confused with the ounce used for weight (avoirdupois ounce). When dealing with water, this volume-to-volume conversion is precise because the density of water is consistent. For other liquids like milk or juice, the volume conversion remains the same, though their weight in ounces will differ slightly due to different densities Most people skip this — try not to..
The Science of Measurement: Fluid Ounces vs. Cups
Why do we have two systems? S. On top of that, usage, the U. On top of that, the fluid ounce, while also a volume unit, has historical roots in both the apothecaries’ and household measurement systems. Now, s. Which means a U. Plus, gallon. S.
