Convert tons to metric tons accurately for international shipping, manufacturing, and commerce. Understand the critical 10% difference between short tons, long tons, and metric tonnes.
1 ton equals 1 metric ton
Formula: t = ton × 0.907185
Understanding the difference between tons and metric tons is essential for international trade and logistics. One metric ton (tonne) equals 1,000 kilograms, while a short ton (US ton) equals 2,000 pounds (907.185 kg). This 10% difference—1 short ton = 0.907185 metric tons—can mean significant cost variations in shipping, manufacturing, and commodity trading worth thousands of dollars per transaction.
The distinction between ton types directly impacts shipping costs, commodity pricing, and regulatory compliance. A 1,000-ton shipment could actually be 907 metric tons or 1,016 metric tons depending on which ton is used. This ambiguity has caused disputes worth millions in international contracts. Precision in ton conversion ensures accurate freight calculations, proper tariff application, and compliance with international maritime and trade regulations.
Maritime and air freight operators worldwide must convert between ton types for accurate billing, capacity planning, and regulatory documentation. Ships measure cargo in metric tonnes, while US-based shippers often quote in short tons. This conversion directly affects freight rates, port fees, and cargo manifests. Errors result in billing disputes and regulatory violations worth thousands per shipment.
Global commodity markets quote prices per ton, but the ton type varies by region and commodity exchange. Iron ore, copper, coal, and steel are traded internationally with prices denominated in different ton types. A single percentage error in ton conversion translates to millions in profit/loss for large-scale mining operations and trading firms. Commodity brokers must maintain precision in all conversions.

This ton to metric ton converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
One short ton equals 2,000 pounds or 907.185 kilograms, while one metric ton equals exactly 1,000 kilograms. The difference is 92.815 kilograms (10.27% heavier for metric tons). In practical terms: 1 short ton = 0.907185 metric tons. For example, a 100-short-ton shipment is actually 90.7185 metric tons, not 100. This distinction is critical for accurate pricing in international trade.
The short ton developed in the US based on the avoirdupois pound system (16 ounces per pound), while the long ton emerged in Britain with different historical weight standards. The metric tonne was introduced in 1795 as part of the decimal metric system. When international maritime law standardized on metric tonnes in the 1960s, the US and UK continued domestic use of their traditional tons, creating ongoing conversion requirements for global commerce and trade agreements.
