تحويل الطن الطويل إلى الطن المتري: الشحن الدولي والنقل البحري والصناعة الثقيلة

One long ton equals exactly 1.01605 metric tons (1,016.047 kilograms). This precise conversion factor comes from the long ton's definition of 2,240 pounds, with each pound equaling 0.453592 kilograms. For example, a 100 long ton shipment converts to 101.605 metric tons. Always use this precise factor for official documentation; approximations like 1.0 or 1.02 cause billing and compliance errors.

The UK and Commonwealth nations (Australia, Canada, South Africa) historically adopted long tons as their maritime standard during the British Empire era. Despite metric system adoption, maritime and mining industries maintained long ton usage due to legacy infrastructure, historical contracts, and established industry practices. Modern regulatory trends increasingly require metric tons, but older documentation and certain industry sectors still reference long tons, necessitating conversion capability for professionals working across different jurisdictions.
