Convert Fluid Ounce (US) to Cubic Inch
Please provide values below to convert fluid ounce (US) [fl oz (US)] to cubic inch [in^3], or vice versa.
Fluid ounce
Definition: A fluid ounce (symbol: fl oz) is a unit of volume in the imperial and United States customary systems of measurement. The US fluid ounce is 1/16 of a US fluid pint, and 1/128 of a US liquid gallon, which is equal to 29.57 mL. The imperial fluid ounce is 1/20 of an imperial pint, and 1/160 of an imperial gallon, which is equal to 28.4 mL.
History/origin: The fluid ounce was originally based on the volume occupied by one ounce (weight) of a given liquid such as wine or water, thus varying based on the system being used. In 1824, the imperial gallon was defined as the volume of ten pounds of water at a temperature of 16.7°C. The imperial gallon's definition was later changed to be equal to 4.54609 liters, making the imperial fluid ounce equal to exactly 28.4130625 mL.
The United States fluid ounce was initially based on the wine gallon used in England prior to 1824. After the adoption of the international inch in 1959, the US fluid ounce became equal to exactly 29.5735295625 mL.
Current use: As the name indicates, the fluid ounce is typically used as a measurement of liquid volume. It is mostly used in the United States and the United Kingdom, as one of the many measurements of volume used.
Cubic inch
Definition: The cubic inch (symbol: in3) is a unit of volume in the Imperial and United States customary systems of measurement. It is the volume of a cube with measurements 1 in × 1 in × 1 in. It is equal to 16.387064 cm3 or mL.
History/origin: The cubic inch is derived from the inch, a unit of length within the imperial and US customary systems of measurement. Since the 1950s and 1960s, with the adoption of the international yard, the inch has been defined as exactly 2.54 cm.
Current use: The cubic inch and cubic foot are still used in the United States, and to some extent in the United Kingdom. However, SI (International System of Units) units of measurement are also widely used throughout these countries.
In the US, the automotive and aircraft industries in particular use the cubic inch to some extent, though the SI derived or SI accepted units of volume (liter, milliliter, and cubic meter) are also used.
In the UK, automotive model numbers are sometimes denoted in cubic inches.
