How to convert Short ton to Tonne
To convert short ton to tonne, multiply the number of short ton by the conversion factor 0.9071847, because 1 ton (US) = 0.9071847 t. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 t = 1.102311 ton (US), so you divide by 0.9071847 (or multiply by 1.102311) to turn tonne back into short ton.
t = ton (US) × 0.9071847 ·
ton (US) = t × 1.102311
- Write down the value you want to convert, in short ton.
- Multiply it by 0.9071847.
- The result is the same area/length/quantity expressed in tonne.

What is a Short ton? History, origin and usage
The short ton is the American answer to an old problem. The British ton of 2,240 pounds came from the tun cask and was awkward to calculate with, so American practice rounded it down to a flat 2,000 pounds — twenty hundredweight of 100 pounds each, rather than twenty of 112. Both survived, which is why "a ton" means two different masses on either side of the Atlantic.
The short ton is the standard bulk weight unit in the United States: freight, coal, steel, gravel, air-conditioning capacity and vehicle ratings are all quoted in it. When an American source says "ton" without qualification, this is almost always the one meant.
The short ton is the lightest of the three tons in common use — lighter than the metric tonne and lighter still than the British long ton. That gap is large enough to matter commercially: the same shipment priced "per ton" is worth noticeably different amounts under the three definitions.
What is a Tonne? History, origin and usage
The word "tonne" comes from the tun, a large medieval wine cask. When the metric system needed a bulk unit, the name was borrowed and the value made round: exactly one thousand kilograms. It was formally recognised as a unit for use with SI in 1879 and remains accepted today, even though its strictly SI name would be the megagram.
Tonnes measure freight, shipping containers, harvests, vehicle weight limits, industrial output and carbon emissions. Almost every country outside the United States means the metric tonne when it says "ton".
Nobody says "megagram", even though that is the coherent SI name for the same mass. In writing, "tonne" or "metric ton" is used to distinguish it from the American short ton and the British long ton, which are both different — and different from each other.

Tips for converting Short ton to Tonne
- To go from short ton to tonne, multiply by 0.9071847; to go back, divide by 0.9071847 (or multiply by 1.102311).
- For a quick mental estimate, remember that 1 short ton ≈ 0.9071847 tonne, so 10 short ton ≈ 9.071847 tonne.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Short ton to Tonne converter
Type a number into the Short ton field and the equivalent in Tonne appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Tonne field to convert the other way (tonne to short ton). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 ton (US) = 0.9071847 t), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for short ton-to-tonne conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary weight units. The 1959 international yard-and-pound agreement fixes the international avoirdupois pound at exactly 0.453 592 37 kilogram, and the ounce, stone, grain and both tons are defined as exact fractions or multiples of that pound — so every imperial weight on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
Weight factors here are exact, anchored to the kilogram: the international pound is exactly 0.45359237 kg, a stone is 14 pounds, a short ton is 2,000 pounds and a long ton is 2,240, a grain is 1/7000 of a pound and a metric carat is exactly 200 mg. So the live tool and every number on this page always agree.
Frequently asked questions
- How many tonne are in 1 short ton?
- 1 short ton = 0.9071847 tonne (t). To convert any number of short ton to tonne, multiply by 0.9071847.
