English-speaking countries also used a system of units of fluid measure, or in modern terminology volume units, based on the apothecaries' system. Originally, the terms and symbols used to describe the volume measurements of liquids were the same as or similar to those used to describe weight measurements of solids [33] (for example, the pound by weight and the fluid pint were both referred to ...
The detection window for body hair cannabis testing will be longer, because body hair grows slower than head hair and distorts the detection timeframe. Hair drug testing measures the marijuana parent metabolite embedded inside the hairshaft and eliminates external contamination as a source of a positive result.
C-6–C-7 The dram apothecaries is equal to 3 scruples (s ap or ℈) or 60 grains (gr), [5]: C-7 or exactly 3.887 9346 grams. [5]: C-14 "Dram" is also used as a measure of the powder charge in a shotgun shell, representing the equivalent of black powder in drams avoirdupois. [16]
Thus, there is no distinction between liquid and dry measure in the imperial system. [according to whom?] The Winchester bushel is the volume of a cylinder 18.5 in (470 mm) in diameter and 8 in (200 mm) high, which gives an irrational number of approximately 2150.4202 cubic inches. [4]
The minim (abbreviated min, ♏︎ or ♍︎) is a unit of volume in both the imperial and U.S. customary systems of measurement. Specifically, in the imperial system, it is 1 ⁄ 60 of an imperial fluid drachm [1] [2] or 1 ⁄ 480 of an imperial fluid ounce; in the U.S. customary system, it is 1 ⁄ 60 of a US customary fluid dram or 1 ⁄ 480 of a US customary fluid ounce.
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 ...
Dry measures are units of volume to measure bulk commodities that are not fluids and that were typically shipped and sold in standardized containers such as barrels.They have largely been replaced by the units used for measuring volumes in the metric system and liquid volumes in the imperial system but are still used for some commodities in the US customary system.
The avoirdupois weight system is thought to have come into use in England around 1300. [citation needed] It was originally used for weighing wool. In the early 14th century several other specialized weight systems were used, including the weight system of the Hanseatic League with a 16-ounce pound of 7200 grains and an 8-ounce mark.
