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.
M stands for Mega (million), g is for gramme (or gram), and ha is for hectare. The â1 part is the equivalent of âperâ. Therefore Mg ha-1 means megagrammes per hectare, to simplify matters, a magagramme is the same as a tonne. A hectare is the same as an area of 10,000 square metres. Mg ha-1 = One tonne per hectare , the same as 100 grammes per square metre (or in old money 4 ounces per square yard).
