A more thorough explanation:

A long ton is a unit of weight measurement that is equal to 2,240 pounds or 1.016 metric tons. It is also known as the "imperial ton" or "weight ton".

For example, if a shipment of goods weighs 5 long tons, it means that it weighs 11,200 pounds or 5.08 metric tons.

The long ton is primarily used in the United Kingdom and other countries that follow the imperial system of measurement. It is different from the short ton, which is used in the United States and is equal to 2,000 pounds or 0.907 metric tons.
