About Cubic centimeter (cm³)
A cubic centimeter (cm³), also written as cc, is the volume of a cube with 1 cm sides, exactly equal to one milliliter (1 cm³ = 1 mL). It is used in medicine for drug dosing, in automotive engineering for engine displacement (a 125 cc scooter engine), and in everyday liquid measurement. The interchangeability of cm³ and mL means a 1 mL syringe and a 1 cc syringe are identical instruments. Engine displacement is expressed in cc for small engines and liters for larger ones (1,000 cc = 1 L).
A standard sugar cube is about 1 cm³. A 1 mL syringe holds exactly 1 cm³. A small motorcycle engine might displace 125 cc.
About Imperial fluid ounce (imp fl oz)
The imperial fluid ounce (imp fl oz) is a unit of volume equal to one twentieth of an imperial pint, approximately 28.413 milliliters. It is used in the United Kingdom and Commonwealth countries, though metric units have replaced it in most commercial contexts. The imperial fluid ounce is slightly smaller than the US fluid ounce (29.574 mL). UK spirits measures are now defined by law in 25 mL and 35 mL metric measures, which do not align exactly with the imperial fluid ounce.
A single spirits measure in a UK bar is 25 mL or 35 mL — close to, but not exactly, one imperial fluid ounce (28.41 mL).
Cubic centimeter – Frequently Asked Questions
Is a cubic centimeter the same as a milliliter?
Yes, 1 cubic centimeter (cm³) is exactly equal to 1 milliliter (mL). The two units are fully interchangeable. Medical syringes marked in mL and those marked in cc hold identical volumes.
What does cc mean in engine displacement?
In engines, cc stands for cubic centimeters and measures the total swept volume of all cylinders. A 125 cc engine has a piston displacement of 125 cm³ per cycle. Larger car engines are stated in liters: 1,000 cc = 1 L.
How many cubic centimeters are in a liter?
There are exactly 1,000 cubic centimeters in one liter. Since 1 cm³ = 1 mL, this also means 1,000 mL = 1 L — a fundamental metric relationship.
Why is cc used in medicine?
Historically, medical equipment used cubic centimeters before the milliliter became standard SI notation. Both are identical in volume. Most clinical guidelines now prefer mL, but cc persists in some specialties and syringe labeling.
How big is 1 cubic centimeter in everyday terms?
A standard sugar cube, a fingertip, or a 1 mL syringe drawn full all represent roughly 1 cm³. A teaspoon holds approximately 5 cm³. A standard shot glass holds about 44 cm³.
Imperial fluid ounce – Frequently Asked Questions
Why did the UK abandon the fluid ounce for spirits but keep the pint for beer?
When the UK metricated in the 1990s, spirits measures were switched to 25 mL and 35 mL because publicans needed precise, legally enforceable pour sizes — and optic dispensers were easy to replace with metric ones. Beer, however, had enormous cultural resistance: the "pint" is deeply embedded in British pub identity, and the Campaign for Real Ale lobbied hard. Parliament granted an explicit exemption allowing draft beer and cider to be sold by the imperial pint. Milk got a similar exemption. The result is a hybrid system where your gin is metric but your beer is imperial.
How many imperial fluid ounces are in a UK pint?
There are exactly 20 imperial fluid ounces in one UK pint (568 mL). In the US system, 1 pint = 16 US fluid ounces (473 mL).
Is the imperial fluid ounce still used?
The imperial fluid ounce is rarely used for commercial transactions in the UK today, which metricated in the 1990s. UK spirits servings are now legally defined in metric (25 mL or 35 mL).
Why is a UK shot 25 mL not one fluid ounce?
When the UK metricated bar measures, the 25 mL "metric measure" replaced older imperial measures. One imperial fl oz (28.41 mL) was not adopted because the EU standardized on 25 mL. So UK shots are not exactly one fl oz.
How many milliliters are in an imperial fluid ounce?
One imperial fluid ounce equals approximately 28.413 mL. One US fluid ounce equals approximately 29.574 mL. Both round to roughly "30 mL" in casual usage, but the precise difference matters in pharmacology.
