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 measurement is a system of measuring using the liter, the gram, and the meter as basic units. The gram is used to measure mass or weight. For instance, a person weighing 170 pounds in customary measurement, weighs 77110 grams or 77.11 kilograms in the metric system. the liter is used to measure capacity. For instance, 1 liter of coke measures about 33.81 ounces in customary measurement.
