There are 2.5 fluid ounces in a 1/3 US cup by weight and volume.
If you are familiar with ounces you will know that it is acceptable to measure liquids with a measuring cup because fluid ounces are constant in standard cup sizes.

For example, a half cup of brown sugar weighs 3.5 ounces and a half cup of butter weighs 4 ounces.
What is an ounce?
An ounce is a unit of measurement used to measure weight, volume, or mass. It is identified or indicated with the ‘oz’ abbreviation.
An ounce is used mainly in the imperial system of measurement which is most commonly found in the United States and in old imperial British measurements.
Though, ounces are now almost only used in the United States (US) and a few other countries like Myanmar.
An ounce is equal to 1/16 of a pound which is approximated to 28.35grams.
Types of ounces
For recipe measurements and the like, there are two main types of ounces which are the fluid ounce and the dry ounce.
The fluid ounce is used to measure the volume of a container while the dry ounce is used to measure the weight or mass of an ingredient on a kitchen scale.
The fluid once is abbreviated to ‘fl oz’ while the dry ounce is indicated with just the ‘oz’ symbol.
If measuring fluid ounces in a container, the measurements are consistent irrespective of the type of liquid being measured.
This means that 2 fluid ounces of water is the same as 2 fluid ounces of milk. It will occupy the same volume in the container. Also, fluid ounces correspond with their weight, for example, 4 fluid ounces of water in a half cup weighs 4 ounces
Dry ounces can vary depending on the weight of the item in the container which is why the dry ounces in one cup of brown sugar and powdered sugar is not the same even though the volume is the same
