Ounce / Grain Units Definition
Ounce
The ounce is a unit of mass whose value is between 25 and 34 grams. It is still used in some countries as the primary unit of measurement and is generally commonly used for the weight of precious metals.
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.
