The US ton, also known as the short ton, is a unit of mass commonly used in the United States. It is defined as exactly 2,000 pounds (avoirdupois). This is equivalent to 907.18474 kilograms.

History of the Ton (US) and Dram
The short ton originated in the English system of weights and measures and became the standard ton in the United States. It differs from the imperial (long) ton (2,240 lbs) used more traditionally in the UK, and the metric ton (1,000 kg).
