A gross ton, also known as a long ton, is a unit of mass equal to 2,240 pounds or 1,016.047 kilograms. This measurement is often used in international shipping and the commodities market, particularly for bulk goods like coal, iron ore, and grain. For instance, a shipment of 5,000 long tons of coal equates to 11,200,000 pounds of coal.
The use of this unit helps standardize large-scale transactions, facilitating clear communication and efficient record-keeping across international borders. Historically rooted in British imperial units, the long ton continues to be relevant in specific industries due to established practices and contractual agreements. Its consistent application provides a reliable basis for pricing, customs duties, and logistical calculations.
