From: pound
To: ton (metric)


Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The avoirdupois pound is equivalent to 16 avoirdupois ounces.

History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the 13th century. It was updated to its current form in 1959. It is a system that was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.

Current use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.


Definition: A ton is a unit of weight and mass. In the United States and Canada, the ton, also known as the short ton, is defined as 2,000 pounds, or 908 kilograms. In the United Kingdom, the ton, sometimes referred to as the long ton, is defined as 2,240 avoirdupois pounds, or 1,016 kg. The tonne, defined in the International System of Units (SI) and also known as the metric ton is defined as 2,204.623 pounds, or 1,000 kilograms.

History/origin: The term "ton" is derived from the "tun," a term that was applied to a large cask that could contain between 175 to 213 imperial gallons, could weigh around 2,000 pounds, and could occupy approximately 60 cubic feet, or 1.7 m3 of space. Although various definitions of the ton are still used in certain countries, the metric ton, or tonne, is the preferred definition of the ton.

Current use: The long ton is used in the United Kingdom along with other countries that still use the imperial system, the short ton is used mainly in the United States, and the tonne is used worldwide. Although both the UK, the US, and some other countries still use other definitions of the ton, the tonne is the legally designated form of the ton for use in trade.
