[1] [2] [3] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F). The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20 °C (68 °F), which is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
In England, a single pub measure (25 ml (0.85 US fl oz)) of a spirit contains one unit. However, a larger 35 ml (1.2 US fl oz) measure is increasingly used (and in particular is standard in Northern Ireland [37]), which contains 1.4 units of alcohol at 40% ABV. Sellers of spirits by the glass must state the capacity of their standard measure in ml.
A measure of spirits [16] in the Ancien Régime of France (before 1795), being 1 ⁄ 32 of a French pinte (~952.1 mL). 1 ⁄ 5 Gill (Scottish) 1 imp fl oz: 28.4 mL: 30 mL: Traditional Scottish spirits measure Peg (India) 1 imp fl oz-28.4 mL: 30 mL: Also called a "small peg"; a "large peg" is a double measure of 2 imperial ounces (60 mL).
The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as 1 ⁄ 3 millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [ 2 ]
A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.

Prior to metrication in the United Kingdom, the standard single measure of spirits in a pub was 1 ⁄ 6 gill (23.7 mL) in England, either 1 ⁄ 5 gill (28.4 mL) or 1 ⁄ 4 gill (35.5 mL) in Scotland, and 1 ⁄ 4 gill (35.5 mL) in Northern Ireland. After metrication, this was replaced by measures of either 25 or 35 millilitres (0.176 or 0.246 gi ...
