What is the 'Normal Distribution'. The normal distribution, also known as the Gaussian or standard normal distribution, is the probability distribution that plots all of its values in a symmetrical fashion, and most of the results are situated around the probability's mean. Values are equally likely to plot either above or below the mean.
Definition of a Mg. A milligram (mg) is a metric system unit that represents a thousandth of a gram. Because of its larger size, a mg is a more commonly used measurement than a mcg. One thousandth of a mg is one mcg, and 1,000 mcg equal one mg.
Milligrams (mg) measure weight, and Millilitres (ml) measure volume of liquid. The part of the word 'Milli' comes from the latin mille, which means one thousand. There are 1,000 milligrams in a gram, and 1,000 millilitres in a litre of liquid.
