how many mg in 1 unit of alcohol
Unit of alcohol One unit of alcohol (UK) is defined as 10 millilitres (8 grams) of pure alcohol.[2][3] Typical drinks (i.e., typical quantities or servings of common alcoholic beverages) may contain 1â€“3 units of alcohol.[3]
Barrel (unit) Fluid barrels vary depending on what is being measured and where. In the UK a beer barrel is 36 imperial gallons (43 US gal; 164 L). In the US most fluid barrels (apart from oil) are 31.5 US gallons (26 imp gal; 119 L) (half a hogshead), but a beer barrel is 31 US gallons (26 imp gal; 117 L).[7][8] The size of beer kegs in the US is based loosely on fractions of the US beer barrel. When referring to beer barrels or kegs in many countries, the term may be used for the commercial package units independent of actual volume, where common range for professional use is 20-60 L, typically a DIN or Euro keg of 50 L.
