1 lb = 0.000453592 t (pound → metric ton)
1 lb = 0.000453592 t
1 pound equals 0.000453592 metric tons. To convert pounds to metric tons, multiply the pound value by 0.000453592. For quick reference: 1 lb = 0.000453592 t, 5 lb = 0.00226796 t, 10 lb = 0.00453592 t, 100 lb = 0.0453592 t.
Metric tons = Pounds × 0.000453592Pounds to metric tonnes multiplies by 0.00045359237 (1 lb = 0.45359237 kg, then ÷ 1000). A 2205 lb load is 1.00016 t; 44 000 lb of US freight is 19.96 t. This conversion converts US shipping and towing figures into the tonnes that international carriers, port authorities, and EU regulations expect. Watch the reverse assumption: a US document saying "22 tons" usually means short tons (2000 lb each = 907.18 kg), so translate the pounds directly rather than trusting a pre-converted ton figure.
US scrap metal and recycling yards buy material by the pound at the counter but report aggregate throughput to regulators in tonnes — 2,000 lb is 0.907 t, 5,000 lb is 2.268 t, and 50,000 lb is 22.68 t. Note this metric tonne is distinct from the US "short ton" of exactly 2,000 lb (0.907 t) that the same yards often use interchangeably in casual conversation; a compliance report using the wrong one will be off by about 10%.

The international avoirdupois pound (lb) is a unit of mass in the imperial and US customary systems, defined as exactly 0.45359237 kilograms since the 1959 international yard and pound agreement. It is the everyday unit for body weight, groceries, and shipping in the United States. Sixteen ounces make one pound; fourteen pounds make one stone in British usage.
The metric ton, or tonne (t), equals exactly 1,000 kilograms. It is the standard unit for industrial shipping, freight, and bulk commodities such as steel, grain, and cement. Despite the name, it is not part of the strict SI system (the SI name is the megagram), but it is universally accepted in commerce and engineering.
