What is a Carat and a Ton (US)?
The carat is a unit of mass used for measuring gemstones and pearls. It is defined as exactly 200 milligrams (0.2 grams).
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.
Note: The Carat is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Ton (US) belongs to the imperial/US customary system.
History of the Carat and Ton (US)
The term "carat" comes from the carob seed ("keration" in Greek), which was historically used as a standard for weighing small quantities due to its perceived uniform weight. The metric carat of 200 mg was adopted internationally in 1907.
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).
