Grain / Mg Units Definition
Grain
The grain is an ancient unit of measurement, either of mass or of length (Gn). It converts a dry unit to wet.The addition of a few grains in addition to the legal weight of a (coin) allowed a coin exposed to wear to retain its legal weight longer; this is what is called the stumbling which allows the balance to be moved1.Originally, this grain could have been a common grain such as a grain of barley, wheat or rye, or a smaller grain2.
Miligram
The milligram (mg) is a unit of weight measurement in the International System of Units (SI). A milligram represents one thousandth of a gram (g). It is a unit commonly used to measure very small quantities of mass, such as doses of medications or the concentration of substances in solutions.
