### Stone

Definition: A stone (symbol: st) is an English and imperial unit of mass. It is defined as 14 pounds or 6.35029318 kilograms.

History/origin: The name "stone" is derived from the use of stones as weights since antiquity. Standardized stones were historically used for trade in England as well as some countries in northern Europe. In England, the stone had multiple definitions throughout history, based on the commodity and on local standards. In 1350, the stone was standardized to be used for wool at a weight of 14 pounds, and in 1835, the United Kingdom adopted this definition for use in the imperial system.

Current use: The stone as a unit of mass is used mostly in the United Kingdom for measuring body weight. Most other countries measure body weight in kilograms, and in some cases, in pounds.

### Milligram

Definition: A milligram is a unit of weight and mass that is based on the SI (International System of Units) base unit of mass, the kilogram. It is equal to 1/1,000 grams, or 1/1,000,000 kilograms.

History/origin: The milligram is based on the SI unit of weight and mass, the kilogram. As an SI unit, it uses the "milli" SI prefix to denote that it is a submultiple of the base unit. Although the "milli" prefix denotes a submultiple with respect to the gram, the kilogram, not the gram, is technically the SI base unit of mass.

Current use: As a submultiple of an SI base unit, the milligram is widely used in many applications, from everyday use to measure the weight or mass of foods, substances, etc., to widespread use in scientific labs, among other areas.
