Convert long tons to kilograms for international shipping, commodity trading, and industrial applications. Accurate calculator with 1 long ton = 1,016.047 kg.
1 long ton equals 1016.0464211288886 kilogram
Formula: kg = long tn × 1016.05
The long ton, also called the imperial ton or British ton, equals 1,016.047 kilograms—significantly heavier than the metric tonne (1,000 kg) or US short ton (907.185 kg). Understanding this distinction is crucial for international trade, maritime commerce, and industrial operations where weight miscalculations can result in regulatory violations, shipping surcharges, or safety hazards. Professionals in shipping, agriculture, and mining must accurately convert between these systems daily.
Weight conversion accuracy directly impacts shipping costs, regulatory compliance, and operational safety. A single long ton conversion error of just 16 kg can accumulate across large shipments—for instance, a 100-ton shipment miscalculated could result in 1,600 kg of unaccounted cargo, violating maritime regulations, triggering unexpected fees, or causing vehicle overload violations. In commodity trading, where prices are calculated per kilogram, this difference translates to thousands of dollars in financial discrepancies.
Port operators and shipping companies use long tons extensively for vessel capacity calculations, cargo manifests, and port authority compliance. UK and Commonwealth ports still predominantly use long tons for official records. When shipping goods internationally, especially to or from UK ports, accurate conversion to kilograms ensures proper documentation, prevents overloading violations, and maintains compliance with international maritime regulations. Miscalculations can result in vessels being detained or cargo being rejected at ports.
Commodity traders dealing with UK-sourced agricultural products, minerals, or industrial materials frequently encounter long ton measurements. Grain dealers, wool exporters, and metal traders must convert between long tons and kilograms for pricing, contracts, and international market transactions. Since commodity prices are typically quoted per kilogram on global markets, accurate conversion is essential for determining true costs and profit margins. A 0.16% conversion error can significantly impact margins on large trades.

One long ton equals exactly 1,016.047 kilograms. This comes from the definition of a long ton as 2,240 pounds avoirdupois, with each pound equaling 453.59237 grams by international agreement. This is approximately 1.6% heavier than a metric tonne (1,000 kg) and 12% heavier than a US short ton (907.185 kg). For quick mental math, remember that a long ton is roughly 1,016 kg or about 1.016 metric tonnes.
Long tons remain in UK maritime law and port operations due to historical precedent and international maritime convention. The International Maritime Organization's regulations reference long tons in official vessel specifications and cargo documentation standards. While modern digital systems display both units, long tons persist because changing centuries-old legal frameworks would require international agreement. Commonwealth ports maintain this system for consistency with UK standards and historical commercial contracts that specify long tons.
