The kg is defined as being equal to the mass of the International Prototype of the Kilogram (IPK), a block of platinum-iridium alloy manufactured in 1889 and stored at the International Bureau of Weights and Measures in Sèvres, France.

It is the only SI unit that is defined by a physical object rather than a fundamental physical property that can be reproduced in laboratories.

st =
kg * 0.15747


The stone is a unit of weight in the imperial system used informally in the UK and Ireland, almost exclusively as a measure of body weight. Although sanctioned by the EU for use as a supplementary unit it is essentially obsolete outside the UK and Ireland.
