Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
A pennyweight (dwt) is a unit of mass equal to 24 grains, 1 ⁄ 20 of a troy ounce, 1 ⁄ 240 of a troy pound, 48 ⁄ 875 avoirdupois ounce [1] and exactly 1.55517384 grams.

By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
The weights are in denominations of 7 pounds (corresponding to a unit known as the clip or wool-clip), 14 pounds (stone), 56 pounds (4 stone) and 91 pounds (1 ⁄ 4 sack or woolsack). [ 18 ] [ 19 ] The 91-pound weight is thought to have been commissioned by Edward III in conjunction with the statute of 1350, while the other weights are thought ...
Convenient "pau" units of both 200 grams and 250 grams are in current use in retail sales in different parts of the country. In Pakistan, the pao was slightly heavier, at 233.3 grams. [6] As to Afghanistan, it was reported in 1950 that 1 pao ≈ 1 lb (450 grams) in Kabul, with four paos to one charak and sixteen paos to a seer. [7]
