The Attic Greek drachma (δραχμή) was a weight of 6 obols, 1 ⁄ 100 Greek mina, or about 4.37 grams. [11] The Roman drachma was a weight of 1 ⁄ 96 Roman pounds, or about 3.41 grams. [12] [13] A coin weighing one drachma is known as a stater, drachm, or drachma.
The conversion factor is 10 8 maxwell per weber, since flux is the integral of field over an area, area having the units of the square of distance, thus 10 4 G/T (magnetic field conversion factor) times the square of 10 2 cm/m (linear distance conversion factor). 10 8 Mx/Wb = 10 4 G/T × (10 2 cm/m) 2.
For historical reasons, the names and symbols for multiples and sub-multiples of the unit of mass are formed as if the gram were the base unit. Prefix names and symbols are attached to the unit name gram and the unit symbol g respectively. For example, 10 −6 kg is written milligram and mg, not microkilogram and μkg. [1]: 144
Recommended Dietary Allowances (RDAs), expressed as milligrams per day, increase with age from 1.2 to 1.5 mg/day for women and from 1.3 to 1.7 mg/day for men. The RDA for pregnancy is 1.9 mg/day, for lactation, 2.0 mg/day. For children ages 1–13 years the RDA increases with age from 0.5 to 1.0 mg/day.
C-19 [9] One gram is thus approximately equivalent to 15.432 36 grains. [6]: C-13 The unit formerly used by jewellers to measure pearls, diamonds, and other precious stones, called the jeweller's grain or pearl grain, is equal to 1 ⁄ 4 carat (50 mg; 0.77 gr). [5] The grain was also the name of a traditional French unit equal to 53.115 mg. [5]
These firecrackers most commonly have a small capsule with up to 50 milligrams of powder (30 milligrams is most common), in contrast with the 5200 milligrams (5.2 g) that real M-80s contain, and a fuse in it. Surrounding the capsule is plaster or a similar material, and finally a red tube and two plastic endcaps.
The sensitivity of the paper is also limited to a detection threshold of 100–200 mg/L while most measurements of "MLF stability" target a malic level of less than 0.03 g/L (30 mg/L). [ 5 ] The enzymatic method allows for a quantitative measurement of both malic and lactic acids, but requires the expense of reagent kits and a spectrophotometer ...
In the metric system, the mass per unit area of all types of paper and paperboard is expressed in terms of grams per square metre (g/m 2 or gsm). This quantity is commonly called grammage in both English and French, [2] though printers in most English-speaking countries still refer to the "weight" of paper.
