Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid is 1.05 times that of water, it has a specific gravity of 1.05. In UK brewing usage, it is customary to regard the reference value for water to be 1000, so the specific gravity of the same example beer would be quoted as 1050.
Was one of the eight standardized US metric bottle sizes listed on January 1, 1980, but was withdrawn on June 30, 1989. Still used in countries that sell wine in half-liters and liters. Bottle (US) 25: 739.3 mL: ≈1 Bottle: Used for domestically produced sparkling white wine in the place of the French metric 750 mL champagne punt.
A 750 ml (25 US fl oz) bottle of 12% ABV wine contains 9 units; 16% ABV wine contains 12 units; a fortified wine such as port at 20% ABV contains 15 units. 100 ml (3.4 US fl oz) glass of wine (13.5% alcohol) = 1 Australian standard drink; 150 ml (5.1 US fl oz) glass of wine (13.5% alcohol) = 1.5 Australian standard drinks
On 1 January 1980, Britain adopted the ABV system of measurement prescribed by the European Union, of which it was then a member. The OIML recommendation for ABV used by the EU states the alcohol by volume in a mixture containing alcohol as a percentage of the total volume of the mixture at a temperature of 293.15 K [20.00 °C; 68.00 °F].
A metric fifth of Dewar's Scotch whisky. A fifth is a unit of volume formerly used for wine and distilled beverages in the United States, equal to one fifth of a US liquid gallon, or 25 + 3 ⁄ 5 U.S. fluid ounces (757 milliliters); it has been superseded by the metric bottle size of 750 mL, [1] sometimes called a metric fifth, which is the standard capacity of wine bottles worldwide and is ...
where TDS is expressed in mg/L and EC is the electrical conductivity in microsiemens per centimeter at 25 °C. The conversion factor k e varies between 0.55 and 0.8. [5] Some TDS meters use an electrical conductivity measurement to the ppm using the above formula. Regarding units, 1 ppm indicates 1 mg of dissolved solids per 1,000 g of water. [6]
The gain in weight is a dry weight measure of the particulates present in the water sample expressed in units derived or calculated from the volume of water filtered (typically milligrams per litre or mg/L). If the water contains an appreciable amount of dissolved substances (as certainly would be the case when measuring TSS in seawater), these ...
Hence 1 L ≡ 0.001 m 3 ≡ 1000 cm 3; and 1 m 3 (i.e. a cubic metre, which is the SI unit for volume) is exactly 1000 L. From 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at maximum density (+3.98 °C) [ citation needed ] and standard pressure .
