* Ounces (oz) measure weight.
* Cups measure volume.
To convert ounces to cups, you need to know the density of the substance you are measuring.
For example:
* Water: 8 fluid ounces (fl oz) equals 1 cup.
* Milk: 8 fluid ounces (fl oz) equals approximately 1 cup.
So, 3 oz of water or milk would be approximately 0.375 cups.
It's important to note that this is just an approximation, and the actual conversion will vary depending on the substance.
