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.
MG vs MCG. The terms âmgâ and âmcgâ are both abbreviations for small units of measurements in the metric system. The term âmgâ stands for the measurement of âmilligramsâ while âmcgâ stands for âmicrograms.â Both units are used to measure an objectâs mass and to indicate an objectâs weight.
