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.
Specific Weight is defined as weight per unit volume. Weight is a force. The SI unit for specific weight is [N/m 3]. The imperial unit is [lb/ft 3]. Specific Weight (or force per unit volume) can be expressed as. Î³ = Ï a g [4] where Î³ = specific weight (N/m 3], [lb/ft 3] Ï = density [kg/m 3], [slugs/ft 3] a g = acceleration of gravity (9.807 [m/s 2], 32.174 [ft/s 2] under normal conditions) What is weight and what is mass? - the difference between weight and mass; Example 5: Specific Weight of Water.
