Unit information

US Liquid Gallon

/ˈlɪkwɪdˈɡalən/

Symbol: gal
Unit system: US Customary

What is the US Liquid Gallon?

The liquid gallon is a unit of volume in the US customary unit system and uses the symbol gal.

It is the most common use of the word gallon and is defined as 231 in³. It is made up of 4 quarts where there are 2 pints in a quart and 16 US fluid ounces in a US pint. There are therefore 128 US fluid ounces in a US gallon.

The term gallon is most prevalent when discussing and trading oil and fuel. To ensure consistency, the temperature of the liquid (typically petroleum or alcohol) is understood to be 15.6 °C (60 °F) at the time of measurement.

Acre Foot

/ˈeɪkə fiːt/

Symbol: ac⋅ft
Unit system: US Customary

What is the Acre Foot?

The acre-foot is a unit of volume in the US customary unit system with the symbol ac⋅ft.

It represents the volume contained in a box measuring 660 feet long, 66 feet wide and 1 foot deep. This can be thought of a box the size of an acre but 1 foot deep.

It is approximately the same volume as an 8 lane swimming pool; 25 metres in length, 3 metres deep and 16 metres wide (assuming lanes are 2 metres wide).

It is still used in the US despite its links to the much-outdated imperial system of units. For example a "rule of thumb" is that an average suburban family's annual water usage should be around 1 acre-foot. This is equal to just under 3.4 m³ daily.
