About these units

Cubic Centimeter (cm³)

Metric (SI)Current unit

Exactly one milliliter. Used for engine displacement (as 'cc') and in medicine.

Cubic centimeter is the volume of a cube one centimeter on each side, and it belonged to the old centimeter-gram-second system of units, in which one cubic centimeter of water was meant to weigh about one gram. Its famous abbreviation, cc, is not an SI symbol at all. The official symbol is cm³, yet cc stuck in medicine, cooking and engineering because it is quick to write and say.

A cubic centimeter equals exactly one milliliter, so the two names are interchangeable and which one you meet depends on the field. Doses are often written in cc. Motorcyclists, scooter makers and engine builders use it for displacement: the swept volume is the bore area times the stroke times the number of cylinders, so a 1,000 cc sport bike can move eight times as much air per cycle as a 125 cc scooter. One cubic inch is 16.38706 cubic centimeters, which lets Americans and Europeans compare engines.

1 cubic centimeter = 0.001 liters (exactly).

Imperial Fluid Ounce (fl oz (UK))

Imperial (British)Current unit

Exactly 28.4130625 mL. About 4% smaller than the US fluid ounce.

Imperial fluid ounce comes from the 1824 reform that defined the British gallon as the volume of ten pounds of water. Because a gallon was set at 160 fluid ounces, an ounce of water weighs about one ounce of mass, around 28.35 grams. That neat link between volume and weight was the point of the imperial scheme, and it explains why people long thought of fluid ounces and weight ounces as nearly the same.

Today an imperial fluid ounce is exactly 28.4130625 milliliters, one twentieth of an imperial pint. That is about 4 percent smaller than the US fluid ounce at 29.57 mL, so a US recipe using fluid ounces does not map one-for-one onto a British one. UK trade rules restricted its use in 1995, and it lives on mostly on older labels, in bars and in recipes. Twenty of them fill an imperial pint, which makes the pint the easiest way to picture one.

1 imperial fluid ounce = 0.0284130625 liters (exactly).
