About Stones and Metric tons
Stones (st): A British unit equal to 14 pounds (about 6.35 kg), originally for trade in raw materials by the stone (literally — large stones used for trade weights). Common uses: British body weight in casual conversation ('I weigh 11 stone 4'), still widely used in the UK and Ireland; not used in the US and rarely in other countries.
Metric tons (t): One thousand kilograms, a metric-system unit standardized in the early 19th century; called a 'tonne' in international SI usage, 'metric ton' in US usage. Common uses: Shipping and freight, industrial commodities (steel, grain, cement), large-scale manufacturing, and emissions accounting (carbon dioxide emissions are reported in metric tons).
