About the stone and the metric ton
The stone
The stone (st) equals exactly 14 pounds (about 6.35 kg). It is still widely used in the United Kingdom and Ireland to state body weight, even though it is no longer legal for trade. The stone was originally a real stone used by merchants as a counterweight on balances; its weight varied by region and trade until standardized in the late 19th century.
The metric ton
The metric ton, or tonne (t), equals exactly 1,000 kilograms. It is the standard unit for industrial shipping, freight, and bulk commodities such as steel, grain, and cement. Despite the name, it is not part of the strict SI system (the SI name is the megagram), but it is universally accepted in commerce and engineering.
