Unit converter
Short tons to kilograms.
Convert short ton to kg and kg to short ton. Type in either box and the other follows. This is the short ton of 2000 pounds, used in the US. The UK long ton is 2240 pounds and the metric tonne is 1000 kg — three different things called a ton.
| short ton | kg |
|---|---|
| 0.5 short ton | 453.592 kg |
| 1 short ton | 907.185 kg |
| 2 short ton | 1814.37 kg |
| 3 short ton | 2721.55 kg |
| 5 short ton | 4535.92 kg |
| 10 short ton | 9071.85 kg |
| 20 short ton | 18143.7 kg |
| 50 short ton | 45359.2 kg |
| 100 short ton | 90718.5 kg |
- Conversion goes through kg in both directions, so neither figure is rounded on the way.
Definitions
- The short ton is 2000 pounds, used in the US. It is 9% lighter than the UK long ton and 9% lighter than the metric tonne.
- The kilogram is the SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
- This conversion is exact by definition. 1 short ton = 907.18474 kg.
- Everything here is mass, not force. The pound is defined as exactly 0.453 592 37 kg, so pound-to-kilogram conversion is exact.
How it works
One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.
The value passes through kg, the unit every other mass & weight unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general mass & weight converter always agree.
Display precision limits significant figures rather than decimal places, because one fixed number of decimals is useless across a range this wide. Very large and very small results switch to scientific notation with a proper superscript exponent. The editable box always holds a plain number at full working precision, so you can carry on from either side.
Common questions this answers: how many kilograms in a ton (short, us) (907.185), how many short tons in a kilogram (0.00110231), and what 5 short ton is in kilograms (4535.92 kg).
