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.
The milligram (mg) and the gram (g) are both measurements of weight or mass in the metric measurement system. One gram is equal to 1000 milligrams. The milliliter (ml) is a measurement of volume in the metric measurement system. One milliliter is equal to 1 gram; there is a 1:1 ratio between the two units of measure.
