<P> Generally, these various meanings do not create confusion because the context is usually sufficient--one being a volume, the others linear or angular measurement . </P> <P> The abbreviation cc (for cubic centimetre, equal to a millilitre or mL) is a unit of the cgs system, that preceded the MKS system, that later evolved into the SI system . The abbreviation cc is still commonly used in many fields including medical dosage and sizing for small combustion engine displacement, such as those used in motorcycles . </P> <P> The microlitre (μL) has been known in the past as the lambda (λ), but this usage is now discouraged . In the medical field the microlitre is sometimes abbreviated as mcL on test results . </P> <P> In the SI system, use of prefixes for powers of 1,000 is preferred and all other multiples discouraged . However, in countries where the metric system was established well before the adoption of the SI standard other multiples were already established, their use remains common . In particular, use of the centi (10), deci (10), deca (10) and hecto (10) prefixes are still common . For example, in many European countries, the hectolitre is the typical unit for production and export volumes of beverages (milk, beer, soft drinks, wine, etc .) and for measuring the size of the catch and quotas for fishing boats; decilitres are common in Switzerland and Scandinavia and sometimes found in cookbooks; centilitres indicate the capacity of drinking glasses and of small bottles . In colloquial Dutch in Belgium, a "vijfentwintiger" and a "drieëndertiger" (literally "twenty - fiver" and "thirty - threer") are the common beer glasses, the corresponding bottles mention 25 cL or 33 cL . Bottles may also be 75 cL or half size at 37.5 cL for' artisanal' brews or 70 cL for wines or spirits . Cans come in 25 cL, 33 cL and 50 cL a.k.a. 0.5 L . </P>
