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.
Weight is the force that mass has because of the gravity. So, if an object has a mass of one pound, then it has the same mass on the moon, but weighs less than earth. In metric system, unit of mass is kilogram. Other common metric mass units are grams, milligrams and tonnes.In imperial and u.s. customary system, common weight units are pound and ounce.o, if an object has a mass of one pound, then it has the same mass on the moon, but weighs less than earth.
