تحويل الأوقية إلى الطن الطويل: الشحن البحري والصناعة والتجارة الدولية

One long ton equals exactly 35,840 ounces, while one short ton equals 32,000 ounces. This 3,840-ounce difference (240 pounds) is significant in maritime and international trade. The long ton is used in UK, Commonwealth nations, and international shipping. The short ton is used in the United States. Confusing these units can result in substantial billing errors and regulatory violations in cross-border trade.

Maritime law and international shipping conventions were established during British naval dominance, standardizing the long ton across global shipping. The International Maritime Organization continues this convention for consistency in vessel specifications, cargo documentation, and port operations worldwide. Although metric tonnes are increasingly used alongside long tons, the long ton remains the official standard for vessel capacity, particularly in Commonwealth nations and traditional maritime hubs.
