Stone

The stone (abbreviation: st.) is a British unit of weight for dry products commonly equivalent to 14 pounds avoirdupois (6.35 kg). In the United Kingdom, the stone continues in customary use for body weight.

England and northern Europe’s other Germanic-speaking countries previously used various standardized “stones” for trade, with their values ranging from about 5 to 40 local pounds (approximately 3 to 15 kg) depending on the objects weighed and location. With the start of metrication, Europe’s various “stones” were replaced by or adapted to the kilogram from the mid-19th century on.

England’s exportation of raw wool to Florence In the 14th century required a fixed standard. A royal statute, in 1389 specified the stone of wool as 14 pounds and the sack of wool as 26 stones. Trade stones of variant weights continue, such as the glass stone of 5 pounds. The stone is still generally used in Britain to define the weights of people and large animals.

Kilogram

In the International System of Units (SI), a kilogram whose symbol is “kg” is the base unit of mass. Nowadays it is defined based on the fixed numerical value of the Planck constant, h, which equals 6.62607015×10-34 in the units of J·s, or kg·m2·s-1. The meter and the second are represented in terms of c, the speed of light, and cesium frequency. The genuine size of the unit remained the same even though the definition of the kilogram was changed in 2019. The changes were intended to enhance the definitions of SI base units(International System of Units).

The name kilogram originated from the French “kilogramme,” which in turn came from adding Greek terminology meaning “a thousand,” in front of the Late Latin term “gramma” which means “a small weight.”

The kilogram is the only SI base unit with an International System of Units prefix. SI is a system based on the meter-kilogram-second system of units instead of a centimeter-gram-second system. 

Originally, in 1794, the kilogram was defined as the mass of one liter of water at its freezing point, although was eventually re-defined, since measuring the mass of a volume of water was inaccurate.

Based on Planck’s constant and changes to the definition of the second, in 2019, a new definition of the kilogram was introduced. This is factual evidence that the mass of the original prototype for the kilogram now weighs 50 (fifty) micrograms less than other copies of the standard kilogram.

As a base unit of SI, the kilogram is used globally in nearly all fields, with the exception of countries like the US, where the kilogram is used in many areas, at least to some degree, such as government, the military, science, and industry.
