Ton

A Ton is a unit of measurement of mass, equaling 2,240 pounds (1,016 kilograms)

Because the ton (of any system of measuring weight) is usually the heaviest unit named in colloquial speech, its name also has figurative uses, singular and plural, informally meaning a large amount or quantity, or to a great degree, as in "There's a ton of bees in this hive," "We have tons of homework," and "I hate seals a ton."
