Kilograms to Hundredweights

There is more than one type of Hundredweights. Please use the appropriate variation from the list below.

  1. Kilograms to Short Hundredweights (US)

  2. Kilograms to Long Hundredweights (UK)


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.
