The gerah was the smallest unit of weight and currency in Biblical Hebrew. It was used for precise measurements and calculations, especially in relation to offerings in the Temple.
A milligram (mg) is a unit of mass in the metric system and the International System of Units (SI). It is equal to one one-thousandth of a gram, which means that 1 milligram is equivalent to 0.001 grams. The milligram is a small unit of mass commonly used for measuring very small quantities of substances, especially in scientific, medical, and pharmaceutical contexts.
For example, when you see the dosage of a medication listed on a prescription or on over-the-counter drugs, it is often measured in milligrams. Additionally, in laboratory settings, chemicals and substances are frequently measured in milligrams due to its precision in measuring small quantities.
