The long ton, also known as the imperial ton or British ton, remains essential in maritime shipping and certain industries. With 1 long ton equaling exactly 1,016,046.9 grams, precise conversion is critical for international commerce, precious metals trading, and heavy cargo documentation where accuracy directly impacts financial transactions and regulatory compliance.
Accurate long ton to gram conversion prevents costly shipping disputes, ensures precious metals are priced correctly, and maintains compliance with international maritime law. A single error of just 1% when converting a 50-ton shipment results in a 508-kilogram discrepancy—potentially worth thousands of dollars in metals trading or causing regulatory violations in customs documentation.
Port authorities and shipping companies use long ton to gram conversions for cargo documentation, billing calculations, and regulatory compliance. International maritime law requires precise weight declarations for container ships, bulk carriers, and general cargo vessels. Errors in conversion lead to customs violations, demurrage charges, and shipping delays that can cost thousands daily.
Gold, silver, and platinum traders work in both grams and long tons depending on transaction scale and market. Refineries receive ore shipments in long tons but process and price metals in grams per troy ounce. Conversion errors directly impact multi-million dollar transactions and require absolute precision in weight declarations.

Exactly 1,016,046.9 grams per long ton. This precise figure comes from the 1959 international definition of the pound as 453.59237 grams, multiplied by 2,240 pounds (the long ton's weight). For precious metals trading requiring maximum precision, use 1,016,046.908 grams. The long ton differs significantly from the metric tonne (1,000,000 grams) and the short ton (907,184.74 grams), so specification is critical in international transactions.
Maritime law and international shipping regulations were established when long tons dominated British naval commerce. These regulations, codified in conventions like the International Convention on Load Lines, continue using long tons for historical continuity and legal precedent. Changing would require updating hundreds of international maritime agreements. Consequently, shipping documents worldwide still reference long tons, though internal systems increasingly convert to metric units for compatibility with modern supply chain software.
