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.
In the metric system, each basic type of measurement (length, weight, capacity) has one basic unit of measure (meter, gram, liter). Conversions are quickly made by multiplying or dividing by factors of 10. It is as simple as moving the decimal point to the right (for smaller prefixes) or to the left (for larger prefixes).
