Reducing the weight of the gold stater to 8.1 grams also allowed to simplify the exchange mechanism between gold and silver, as now 1 gold stater of 8.1 grams corresponded precisely in value to 10 silver staters of 10.7 grams, or to 20 silver coins of 5.35 grams (weight of the future Achaemenid Siglos), since the current exchange rate on a ...

The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
From the Middle Kingdom date deben weight units used for particular metals, referred to as copper deben and gold deben, the former being about twice as heavy (27 g (0.95 oz; 0.87 ozt)) as the latter. Such weights from the Middle Kingdom were discovered at Lisht , using gold deben, [ 6 ] and copper deben.

The established abundances of chemical elements in urban soils can be considered a geochemical (ecological and geochemical) characteristic, the accumulated impact of technogenic and natural processes at the beginning of the 21st century.
[j] The total amount of astatine in the Earth's crust (quoted mass 2.36 × 10 25 grams) [108] is estimated by some to be less than one gram at any given time. [8] Other sources estimate the amount of ephemeral astatine, present on earth at any given moment, to be up to one ounce [ 109 ] (about 28 grams).
