Wordwide use:

Long tons, also known as imperial tons, are a unit of measurement commonly used in the United Kingdom and other countries that were once part of the British Empire. One long ton is equivalent to 2,240 pounds or 1,016 kilograms. Despite being primarily used in the UK, long tons are also recognized and used in some other parts of the world.


The long ton, also known as the imperial ton or the gross ton, is defined as 2,240 pounds or approximately 1,016.05 kilograms. The long ton is derived from the traditional British system of weights and measures, which was widely used before the adoption of the metric system. It is important to note that the long ton differs from the short ton used in the United States, which is equal to 2,000 pounds or approximately 907.18 kilograms. The distinction between the two tons is crucial when dealing with international trade and transportation, as it ensures accurate measurement and avoids confusion.


The origin of the long ton as a unit of measurement can be traced back to medieval England. In those times, goods were often weighed using a system known as the "hundredweight," which was equal to 112 pounds. This hundredweight was further divided into four quarters, each weighing 28 pounds. The long ton was derived from this system by multiplying the hundredweight by 20, resulting in a weight of 2,240 pounds. This unit was primarily used for measuring heavy commodities such as coal, iron, and other raw materials.

Usage context:

The long ton (UK) is primarily found in industries such as shipping, mining, and agriculture. In the shipping industry, long tons are often used to measure the weight of cargo, especially for large vessels carrying bulk goods like coal, iron ore, or grain. This unit is particularly important for international trade, as it allows for standardized measurements and calculations when determining the capacity of ships or negotiating freight rates.

In the mining sector, long tons are commonly used to measure the weight of extracted minerals or ores. This is especially relevant in countries with a long history of mining, such as the United Kingdom itself. The use of long tons (UK) ensures consistency and accuracy in reporting production figures and estimating reserves.

In agriculture, long tons are employed to measure the weight of crops, livestock, or agricultural products. This is particularly relevant for commodities like wheat, barley, or sugar beets, which are often traded in bulk quantities. Farmers, traders, and processors rely on long tons to determine the value and quantity of their produce, facilitating fair transactions and efficient supply chain management.
