The International Mass and Length Units

The International Mass and Length Units are units based on the international yard and the international pound.

They were created in 1959 when Australia, Canada, New Zealand, South Africa, the United Kingdom and the United States of America agreed upon a common definition of the yard and the pound.

The kilogram (kg) is the base unit of mass in the International System of Units.

Definition of the kilogram

It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 x 10^–34 when expressed in the unit J s, which is equal to kg m² s^–1, where the metre and the second are defined in terms of c and ∆ν_Cs.

Definition from the BIPM: Unit of mass

History

The first definition of the kilogram was "the mass of a liter of water". But this proved impractical and in 1889, the International Prototype Kilogram, a cylinder of platinum-iridium alloy, was made to serve as the reference.

In 1949 the mass of the IPK was found to be deverging from its copies. So, in order to ensure the stability of the unit, a new definition was devised based on the Planck constant and on 20 May 2019 this new definition came into effect.

Some Facts

With an average of 1.4 kg (3 lbs), ostrich eggs are huge, yet, they are the smallest eggs relative to the size of the adult bird.

Prefix

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
