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 U.S. Customary System consists of: ounces, pounds and tons 16 oz = 1 lb 2000 lb = 1 ton The Metric System consists of: kilograms, grams (the base unit) and milligrams 1 kg = 1000 g 1 g = 1000 mg Just to give an idea of mass... The mass of a paperclip is about 1 gram and the mass of a textbook is about 1 kg.In addition, 1 kg is about 2.2 lbs. The mass of a paperclip is about 1 gram and the mass of a textbook is about 1 kg.In addition, 1 kg is about 2.2 lbs. Click here to practice identifying mass within the U.S. Customary System and the Metric System.o determine mass we can use one of two systems-the U.S. Customary System and the Metric System. The U.S. Customary System consists of: ounces, pounds and tons 16 oz = 1 lb 2000 lb = 1 ton.
