Unit converter

Kilograms to short tons.

Convert kg to short ton and short ton to kg. Type in either box and the other follows. Gives short (US) tons. For metric tonnes just divide by 1000, and for UK long tons use the long-ton entry in the menu.

Definitions

  • 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.
  • 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.
  • This conversion is exact by definition. 1 kg = 0.001102311311 short ton.
  • 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 short tons in a kilogram (0.00110231), how many kilograms in a ton (short, us) (907.185), and what 5000 kg is in short tons (5.51156 short ton).
