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 ton (also known as the tonne) is a metric unit of weight equal to 1,000kg (1 megagram, a term that is almost never used). It is a non SI unit that is in common usage given that it is equal to 2,204.6 lbs which is close to the UK imperial ton (2,240lb) and the US customary units ton (2,000lb).he metric ton (also known as the tonne) is a metric unit of weight equal to 1,000kg (1 megagram, a term that is almost never used).
