The US fluid ounce is based on the US gallon, which in turn is based on the wine gallon of 231 cubic inches that was used in the United Kingdom prior to 1824. With the adoption of the international inch, the US fluid ounce became 1⁄128 gal × 231 in 3 /gal × (2.54 cm/in) 3 = 29.5735295625 mL exactly, or about 4% larger than the imperial unit.
The 21 grams experiment refers to a study published in 1907 by Duncan MacDougall, a physician from Haverhill, Massachusetts.

A standard size tin can holds roughly 400 g; though the weight can vary between 385 g and 425 g depending on the density of the contents.
There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1 / 128 of a US gallon. In order to overcome the effects of expansion and contraction with temperature when using a gallon to specify a quantity of material for purposes of trade, it is common to define ...
The Babylonian system, which the Israelites followed, measured weight with units of the talent, mina, shekel (Hebrew: שקל), and giru, related to one another as follows: 1 shekel = 24 giru. 1 mina = 60 shekels (later 100 zuz) 1 talent = 60 mina. In the Israelite system, the ratio of the giru to the shekel was altered, and the talent, mina ...
