Facts about the Ounce
The ounce is a unit of mass in the imperial system, commonly used in the U.S. and U.K., equal to approximately 28.3495 grams.
Historically, the ounce varied in value depending on region and use (troy, apothecaries, or avoirdupois). The common avoirdupois ounce, now standardized, remains in wide use.

Facts about the Milligram
A milligram is a unit of mass in the metric system equal to one-thousandth (1/1000) of a gram or one-millionth (1/1,000,000) of a kilogram.
Milligrams became essential with the advancement of pharmaceutical and chemical sciences, providing a highly accurate and precise way to quantify very small masses.
Primarily used in pharmaceuticals, chemistry, and food supplements. Many medications are dosed in milligrams due to the precision required for safe consumption.
