The short answer

How do you convert kilograms to US short tons?

To convert kilograms to US short tons, divide the kilograms by 907.18474, because one short ton is defined as 2,000 pounds, which equals 907.18474 kilograms exactly. So 907.18474 kg = 1 short ton, and 2,000 kg ≈ 2.2046 short tons. The US short ton is the 'ton' used by default in the United States — for freight, scrap metal, aggregates and agriculture — and it is noticeably lighter than the metric ton (1,000 kg) and the UK long ton (1,016.0469 kg). This distinction matters commercially: quoting a price 'per ton' means a different quantity on each side of the Atlantic — a difference of roughly 10% — so cross-border contracts should always name which ton they mean. Enter any kilogram amount above to get the exact short-ton value, or flip the direction toggle to convert US short tons back to kilograms.

Formula & method

Methodology

Accuracy & assumptions

Every calculator makes assumptions. Here are ours, stated plainly, so you know exactly what the numbers do and do not account for.

  • One US short ton is exactly 2,000 pounds = 907.18474 kg (using 1 lb = 0.45359237 kg).

  • 'Short ton', 'US ton' and 'net ton' all refer to this same 907.18474 kg unit.

  • This is not the metric ton (1,000 kg) or the UK long ton (1,016.0469 kg).

Conventions follow the SI (International System of Units), maintained by the BIPM, with US customary values published by NIST. Every result is derived from the exact kilogram-to-ton constants, so figures match the definitions rather than rounded approximations.

Primary sources

Where these rules come from

The conventions this calculator follows are set by international standards bodies, not by us. Each one links to the issuing body so you can check it rather than take our word for it.

Details

What are the key details?

Scannable facts worth knowing before you convert or compare a ton figure.

  • The short ton is the standard 'ton' in US domestic trade — freight, scrap, aggregates and produce.

  • It is defined from the avoirdupois pound, so the kilogram factor (907.18474) is exact but not round.

  • A short ton is about 10.2% lighter than a metric ton and about 10.7% lighter than a long ton.

  • In the US, an unqualified 'ton' almost always means a short ton; elsewhere it means a metric ton.
