The notion of normal distribution, being one of the most important distributions in probability theory, has been extended far beyond the standard framework of the univariate (that is one-dimensional) case (Case 1).
The metric unit of weight (or any other force such as that of a  stretched spring, or a bat striking a ball, or a locomotive pulling  a train) is called the newton.   Neâ¦wton is the unit of weight (exactly of force) in the SI; in base  units is kg.m/s2.
The metric units most used to express mass are the kilogram and the  gram. A kilogram is equal to 1000 grams. A kilogram also is  equivalent to 2.2 pounds. Other metric unitâ¦s of mass are the  milligram and the centigram.
