What is a US fluid ounce?

A US fluid ounce is a volume unit in the United States customary system equal to 1/128 of a US liquid gallon, about 29.5735295625 milliliters.

What is a tun used for?

A tun is a traditional English unit for large liquid volumes, historically used to describe large wine or ale cask capacities and in old customs and trade records.

Why does the tun volume vary?

The tun’s size has varied regionally and over time due to changes in the definition of the gallon, so its volume differs in historical sources compared to modern approximations.
