The system can be traced back to the measuring systems of the Hindus [18]: B-9 and the ancient Egyptians, who subdivided the hekat (about 4.8 litres) into parts of 1 ⁄ 2, 1 ⁄ 4, 1 ⁄ 8, 1 ⁄ 16, 1 ⁄ 32, and 1 ⁄ 64 (1 ro, or mouthful, or about 14.5 ml), [19] and the hin similarly down to 1 ⁄ 32 (1 ro) using hieratic notation, [20] as ...
The 1707 British statute defines the wine gallon as 231 cubic inches (3,790 cm 3) – e.g. a cylinder 7 inches (178 mm) in diameter and 6 inches (152 mm) high, [nb 1] c. 3.785 litre – and was used to measure the volume of wine and other commercial liquids such as cooking oils and honey. [4] A 14th-century barrel of wine contained 31.5 US gal ...
The tun (Old English: tunne, Latin: tunellus, Middle Latin: tunna) is an English unit of liquid volume (not weight), used for measuring wine, oil or honey.It is typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used.
The chart below [6] lists the sizes of various wine bottles in multiples relating to a standard bottle of wine, which is 0.75 litres (0.20 US gal; 0.16 imp gal) (six 125 mL servings). The "wineglassful"—an official unit of the apothecaries' system of weights —is much smaller at 2.5 imp fl oz (71 mL ).
A hogshead of brandy was approximately equal to 56–61 gallons (0.255–0.277 m 3). [ citation needed ] Eventually, a hogshead of wine came to be 52.5 imperial gallons (238.669725 L ) (63 US gallons), while a hogshead of beer or ale came to be 54 gallons (249.5421 L with the pre-1824 beer and ale gallon, or 245.48886 L with the imperial gallon).
One litre of liquid water has a mass of almost exactly one kilogram, due to the gram being defined in 1795 as one cubic centimetre of water at the temperature of melting ice. [4] The original decimetre length was 44.344 lignes, which was revised in 1798 to 44.3296 lignes. This made the original litre 1.000 974 of today's cubic decimetre. It was ...
For example, to make 100 mL of 50% alc/vol ethanol solution, water would be added to 50 mL of ethanol to make up exactly 100 mL. Whereas to make a 50% v/v ethanol solution, 50 mL of ethanol and 50 mL of water could be mixed but the resulting volume of solution will measure less than 100 mL due to the change of volume on mixing, and will contain ...
The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined in 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 °C ...
