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.
In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.

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 picul / ˈ p ɪ k əl /, [1] dan [2] or tam, [3] is a traditional Asian unit of weight, defined as "as much as a man can carry on a shoulder-pole". [1] Historically, it was defined as equivalent to 100 or 120 catties, depending on time and region.
The inductance of a closed circuit that produces one volt of electromotive force when the current in the circuit varies at a uniform rate of one ampere per second. [ 32 ] = 1 H = 1 Wb/A = 1 kg⋅m 2 /(A⋅s) 2
