One metric ton is 2,204.62262 pounds

One metric ton is 2,204.62262 pounds. The metric ton is the megagram: 1,000 kilograms, or 1,000,000 grams. Multiply any tonne figure by 2,204.62262 and the answer is in pounds. Divide pounds by the same figure and they come back in tonnes.

NIST, SI Units of Mass states the metric ton as 1,000 kilograms, and the general table in NIST Handbook 44, Appendix C (2024 edition) prints the pound equivalent as 2 204.623. The longer figure on this page, 2,204.62262, is that same value carried out to five decimals, and it comes from a division shown in the third section below.

Nothing about a tonne is small. A single tonne outweighs a family car, a pallet of bricks or a stack of steel plate, so the pounds column on every table here runs into four and five digits. That is why freight paperwork often drops the last decimals and why a 0.5 percent error turns into a hundred pounds on one truck.

The right hand column is the one that catches people out. A metric ton is heavier than a US short ton, so 25 metric tons is 27.56 short tons, not 25. The next section keeps the three tons apart.

Three different units share the name ton

English uses one word for three weights, and on a freight dock that word decides money. The short ton is 2,000 lb exactly and is the default in the United States. The long ton is 2,240 lb exactly and survives in UK shipping and in some coal and scrap contracts. The metric ton is 1,000 kg, which works out to 2,204.62262 lb.

Written as tonnes, the short ton is 0.90718474 t and the long ton is 1.0160469 t. The gap between a metric ton and a short ton is 204.62262 lb, about 92.8 kg, which is roughly one adult passenger. Load 20 short tons onto a scale calibrated in metric tons and the ticket reads 18.14 t, a shortfall a driver will notice at a weigh station.

The spelling helps in writing and not in speech. A quote in "tonnes" is metric, a quote in "tons" from a US mill is short tons, and a bill of lading from a UK broker may mean long tons while printing neither adjective. Ask which one before signing, because the spread between the smallest and the largest is 240 lb per unit.

One more unit sits next to these on a scale ticket: the hundredweight, or cwt. The US hundredweight is 100 lb, and 20 of them make a short ton. Scrap and steel prices are quoted per cwt in the United States, so a price per cwt converts to a price per metric ton by multiplying by 22.0462.

Where 2,204.62262 comes from

The figure is one division. A metric ton is 1,000,000 g. A pound is 453.59237 g exactly, fixed by the 1959 agreement between the United States, the United Kingdom, Canada, Australia and New Zealand. Divide the first by the second and the pound count falls out: 1,000,000 / 453.59237 = 2,204.62262.

The other route gives the same answer. One kilogram is 2.20462262 lb, so 1,000 of them are 2,204.62262 lb. Both paths use the same pound definition, which is why the fourth decimal never disagrees between a metric scale and an imperial one.

The kilogram itself changed in 2019, when the SI redefined it through the Planck constant instead of a metal cylinder in France. That change did not move the pound. The 1959 pound is still 0.45359237 kg by definition, so the tonne to pound figure on this page is unaffected by the redefinition, and the BIPM SI Brochure keeps the tonne as a non-SI unit accepted for use with the SI.

One consequence matters on a ticket. Because the pound is defined from the kilogram, a US scale and a European scale are not two independent instruments that happen to agree. They agree because the conversion is exact, and any difference between their readings comes from the instruments, not from the units.

Container ratings and the 80,000 lb highway cap

Freight is where tonne to pound arithmetic gets checked by a machine. A 20 foot ISO container is rated at a maximum gross weight of 30,480 kg, which is 67,196.9 lb. The box itself weighs about 2,200 kg, or 4,850.2 lb, so the cargo inside can be 28,280 kg, which is 62,346.7 lb.

A 40 foot container carries the same 30,480 kg rating on most standard boxes, and its own tare is heavier at about 3,750 kg, or 8,267.3 lb. The payload drops to 26,730 kg, or 58,929.6 lb. The longer box holds more volume and less weight, a detail that surprises anyone shipping foam or furniture.

Road limits are written in pounds in the United States. The federal gross vehicle weight limit on the interstate system is 80,000 lb, which is 36.287 metric tons. A tractor and trailer pair takes about 35,000 lb of that before any cargo is loaded, leaving roughly 45,000 lb, or 20.4 t, for the load. That is why a 25 t shipment needs a permit or a second truck even though the trailer looks half empty.

Axle rules sit under the gross limit. A tandem axle group is commonly limited to 34,000 lb, which is 15.42 t, so a dense load of steel coils can break a rule while staying under the 80,000 lb total. Weight is checked per axle, and the tonne figure on the shipper's paperwork is not what the scale prints.

Grain and oilseed: bushels inside a tonne

Grain is sold by the bushel in the United States, and a bushel is a volume that becomes a weight only when a standard weight per bushel is applied. The USDA Agricultural Marketing Service publishes those standard weights, and they are what a elevator uses when it converts a scale ticket into bushels.

Wheat is 60 lb per bushel, so one metric ton of wheat is 36.744 bushels. Corn is 56 lb per bushel, so a tonne of corn is 39.368 bushels. Soybeans are 60 lb per bushel and land on the same 36.744 as wheat. Barley at 48 lb per bushel gives 45.93 bushels per tonne.

The division is worth writing out once. For corn, 2,204.62262 / 56 = 39.368 bushels. For wheat, 2,204.62262 / 60 = 36.744 bushels. A 30 t hopper of corn is 1,181.05 bushels, and the same 30 t of wheat is 1,102.3 bushels, a gap of nearly 79 bushels on one load.

Metric markets skip the bushel and quote grain per tonne, which is why an export contract can read 50,000 t and a country elevator's ticket can read 1,968,400 bushels for the same corn. Neither number is wrong. They are the same pile weighed under two conventions, and the 56 lb bushel is the bridge between them.

Steel, scrap and the price per hundredweight

US steel and scrap prices are quoted per hundredweight, written cwt, and one cwt is 100 lb. A metric ton holds 22.0462 of them, because 2,204.62262 / 100 = 22.0462. A mill quote of $42 per cwt becomes $925.94 per metric ton, since 42 x 22.0462 = 925.94.

That multiplier is the only thing standing between two price sheets that look unrelated. A scrap yard paying $280 per short ton is paying $308.65 per metric ton, because the short ton and the tonne differ by 10.2 percent. Read the unit before comparing two bids, and read it twice when the bid is large.

Length units convert the same way for rebar and coil. A number 4 rebar weighs 0.668 lb per foot, so a metric ton of it runs 3,300.3 ft, from 2,204.62262 / 0.668. The same bar in a metric spec is 0.994 kg per meter, and 1,000 kg of it runs about 1,006 m, which matches the 3,300 ft figure within a fraction of a percent and is a good check that both tables describe the same steel.

Plate is sold by the pound in the United States and by the tonne in Europe, and the density does the rest. A 3/8 inch plate weighs 15.3 lb per square foot, so a tonne covers 144.1 sq ft, from 2,204.62262 / 15.3. Order the same plate in metric and the mill quotes 75 kg per square meter, which is the same 15.3 lb per square foot within rounding.

Weight tickets: gross, tare and net in tonnes

A truck scale prints three numbers: gross, tare and net. Gross is the loaded truck, tare is the empty truck, and net is the difference. All three arrive in pounds at a US scale house and all three may need to be in tonnes on a customs form or an export document.

The subtraction happens in pounds, then the conversion happens once on the net. Doing it the other way, converting both weights and then subtracting, works too but invites a rounding error on each of the two figures instead of one.

The net of 50,400 lb is 22.861 t, from 50,400 / 2,204.62262. Check the subtraction first, because a transposed digit on a ticket is more common than a unit error. 78,000 minus 27,600 is 50,400, and that is the number the invoice should use.

Rail moves the same arithmetic to a larger scale. A covered hopper car holds about 100 short tons of grain, which is 200,000 lb, and that is 90.718 metric tons. A 110 car unit train therefore carries roughly 9,979 t, and the export terminal's berth plan is written in those tonnes rather than in pounds.

Rounded factors and the cost on a heavy load

Rounding 2,204.62262 to 2,200 is a 4.62262 lb error per tonne. On one tonne that is a rounding choice. On a train it is a different shipment.

At 40 t the shortcut is 184.9 lb light, which is 83.9 kg, and that is enough to put a container over a rated payload when the load was planned to the last pallet. At 100 t it is 462.26 lb, near a quarter of a short ton.

Rounding to 2,204.6 is a different size of error. The gap is 0.02262 lb per tonne, so 100 t comes out 2.26 lb light, and 1,000 t comes out 22.6 lb light. Four decimal places cover almost every commercial load, and six cover a laboratory.

Two habits remove the risk. Keep the constant at 2.20462262 lb per kilogram and multiply by 1,000 for tonnes, which is one more digit than the shortcut and no more work. Or convert to kilograms first, since a metric scale is often the one on site, and leave the pounds to the invoice software that already stores the full constant.
