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 basic metric unit of mass is the kilogram (kg). Kilograms are the only basic unit to contain a metric prefix. For quantifying small masses, grams (g) or milligrams (mg) are used instead.Micrograms (Âµg) are used in microbiology and other laboratory work for extremely small masses.he basic metric unit of mass is the kilogram (kg). Kilograms are the only basic unit to contain a metric prefix. For quantifying small masses, grams (g) or milligrams (mg) are used instead.
