The weight in US short tons of 2,000 lb.

Three tons are in common use: the short ton (2,000 lb), the metric tonne (1,000 kg, about 2,205 lb) and the imperial long ton (2,240 lb). A quote saying only 'tons' is ambiguous.

Weight

9.072 tonnes

High confidence

1 short ton = 2,000 lb = 907.18474 kg = 0.90718474 tonnes. Three different tons are in circulation and they span about 12% — never accept an unqualified 'ton' on a cross-border quote.

How this was calculated

Formula source(s)

  • 1 short ton = 2,000 lb; 1 lb = 0.45359237 kg; so 1 short ton = 0.90718474 metric tonnes
  • 1 imperial long ton = 2,240 lb = 1.016047 metric tonnes

Confidence note: 1 short ton = 2,000 lb = 907.18474 kg = 0.90718474 tonnes. Three different tons are in circulation and they span about 12% — never accept an unqualified 'ton' on a cross-border quote.

What this calculation does not cover

  • This converts the SHORT ton of 2,000 lb. An imperial long ton is 2,240 lb and converts to 1.016 tonnes, so a figure quoted in a British or older specification read as a short ton is about 12% light.
  • A ticket reading 'ton' rarely says which. Aggregate and steel are commonly quoted in short tons in the United States and in tonnes almost everywhere else, and the word alone does not settle it.

Bulk material quotes and haulage limits both use the word ton for units that differ by up to twelve percent, which makes this one of the more consequential conversions on the site. A short ton is two thousand pounds, a metric tonne is a thousand kilograms at about 2,205 pounds, and the imperial long ton is 2,240 pounds. American aggregate is priced in the first, European and Australian in the second, and older British documentation in the third. On a cross-border order the difference is roughly a tenth of the material, and on a vehicle weight limit it is the difference between legal and overloaded, so an unqualified figure is worth querying rather than converting.

Called something else where you work? Ton / tonne — the term in each market, how close the equivalence really is, and the standard that governs it.

Frequently asked questions

How many tons are there?
Three in common use. The short ton is 2,000 lb and standard in the US. The metric tonne is 1,000 kg, about 2,205 lb. The imperial long ton is 2,240 lb and still appears in older British material. They span about twelve percent between them.
Which does an aggregate quote mean?
In the US, almost always short tons. In the UK, Europe and Australia, metric tonnes. Cross-border quotes should say explicitly, and where they do not it is worth asking rather than assuming — the difference is roughly a tenth of the order.
Do haulage weight limits use the same ton?
They follow local convention, so a US gross vehicle weight rating is in pounds or short tons while a European one is in tonnes. Converting a payload figure without checking which ton the limit uses can put a vehicle over its legal weight.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
