Whether in singular or plural form, the only way to abbreviate the ounce is to combine the letters ‘o’ and ‘z’. So, the abbreviation of an ounce is ‘oz’. There is a school of thought that the abbreviation of an ounce can be traced to the middle-aged Italians of the old Roman Empire. This abbreviation also has strong links with the old Latin language. The origin of the abbreviation is from the word extinct Latin word “uncia” which was letter translated by the Italians to be “onza”. “Uncia” was used to represent one twelfth of the Roman libra. So, the abbreviation of this unit is basically a selection of some letters from its translation to other languages.

Fluid Ounce

A fluid ounce is used to measure the volume of liquid matter. There is a difference between an ounce and fluid ounce.

Understanding the differences that exist between them will save you from embarrassment and humiliation.

The fluid ounce is often abbreviated as fl oz, or fl. oz. In the American system of measurement, a fluid ounce is equal to 1/16 of an American fluid pint while in the imperial system of measurement; a fluid ounce is 1/20 of a pint.

The imperial gallon (UK)

In Britain, an imperial gallon is approximately equal to 277.42 cubic inches or 4.55 liters. Before the imperial gallon, the people of Britain used other units to measure volume. Some of these units include the Winchester gallon (which was sometimes referred to as the corn gallon), Jersey gallon, and wine gallon.

The imperial gallon is not only used as a unit of measurement in Britain. Some other Commonwealth countries also use it as a standard for measuring volume. The value of an imperial gallon used to be relative to the value of a certain amount of water (usually 10pounds) under a specific condition of temperature and pressure.

Fluid Measurement Difference Between UK and US

There is a difference in the fluid measurement between UK and US.

US

1 Gallon (US, Fluid) = 3.785 liters

1 Liters = 33.814 ounces (US fluid)

1 fluid Gallon = 3.785 x 33.814 = 128 ounces

1 U.S. gallon is equal to 128 U.S. fluid ounces.

So 1/ 2 U.S. gallon is equal to 64 U.S fluid ounces.

UK

1 Gallon (UK, Fluid) = 4.54609 liters

1 Liters = 35.1951 ounces (UK fluid)

1 fluid Gallon = 4.54609 x 35.1951 = 160 ounces

1 U.K. gallon is equal to 160 U.K. fluid ounces.

The American liquid gallon isn’t as heavy as the imperial gallon. It equals 231 cubic inches which are almost 3.79 liters. It is also equal to 1/128 of the standard US gallon. When the American liquid gallon is used to refer to the volume of any product, the usual practice is for the prevailing temperature and pressure to be included. This is because volume changes with a slight alteration in these two other factors. For instance, when we refer to the volume of an alcoholic beverage or a petroleum product, it is usually assumed that the temperature is 15.6oC.

The U.S. dry gallon

The US dry gallon is another unit of measurement of volume. It is a measure of the capacity of dry material and approximately equals 4.404 liters. It is also equal to 1/8 of 2150 cubic inches, which is the value of a Winchester bushel.
