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.
One milligram is equal to one millionth of the kilogram (kg), which is the current SI (Metric system) base unit of mass. 1 milligram (mg) = 1000 microgram (mcg or Âµg) = 0.000001 kilogram (kg) = 0.001 grams (g) = 0.0000352739619 ounces (oz) = 0.00000220462262 pounds (lb).
