The catty or kati is a traditional Chinese unit of mass used across East and Southeast Asia, notably for weighing food and other groceries. Related units include the picul, equal to 100 catties, and the tael, which is 1 ⁄ 16 of a catty. A stone is a former unit used in Hong Kong equal to 120 catties and a gwan (鈞) is 30 catties.
Similarly, Singapore law stipulates that one jin, or "catty", is also equal to 1 1⁄3 pounds, which is equal to sixteen liangs (or "taels") or 0.6048 kilograms. [7] Malaysia has the same regulations as it is a former British colony. The word "catty" comes from Malay kati, meaning "the weight".
The Hong Kong SAR continues to use its traditional units, now legally defined based on a local equation with metric units. For instance, the Hong Kong catty is precisely 604.789 82 g. Note: The names lí (釐 or 厘) and fēn (分) for small units are the same for length, area, and mass; however, they refer to different kinds of measurements.

Epoxy value derives from the Epoxy equivalent weight (EEW) or Weight Per Epoxide (WPE) and is a measure of the epoxy content of an epoxy resin or epoxy reactive diluent, or glycidyl ether. [1] This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent. [ 2 ]
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2]
The amine value is useful in helping determine the correct stoichiometry of a two component amine cure epoxy resin system. [6] [7] [8]It is the number of Nitrogens x 56.1 (Mwt of KOH) x 1000 (convert to milligrams) divided by molecular mass of the amine functional compound.
A common commercial weight, the Caoping (漕平; cáopíng; 'canal shipping standard') tael weighed 36.7 grams (1.18 ozt) of marginally less pure silver. As in China, other parts of East Asia such as Japan and Korea have also used the tael ( Japanese : 両 ; rōmaji : ryō ; Korean : 량/냥 (兩) ; romaja : nyang/ryang ) as both a unit of ...
