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 SI base unit for mass is the kilogram. The SI derived unit for weight or force is the newton. 1 kilogram is equal to 1000000000 ug.
