Metre Convention describes the 1875 treaty and its development to the modern day.

The metre convention was originally drawn up with the main purpose of providing a standards of length and mass only.

In that year, seventeen nations signed the Metre Convention and the management and administraion of the system passed into international control.

On 26 October 2012, Colombia announced that she would be signing the Metre Convention.

The original aim of the Metre Convention - the worldwide uniformity of measurement - remains as important today as it was in 1875.

There have been several modifications to the definitions of the base units, and additions of base units, since the Metre Convention in 1875.

World Metrology Day celebrates the signature by representatives of seventeen nations of the Metre Convention on 20 May 1875.

International system of units (SI) is system of units that has been officially endorsed under the Metre Convention since 1960.

Britain was initially involved in the development of the metric system, and the US was among the 17 initial signatories of the Metre Convention in 1875.

The original batch of 40 prototypes (adopted in 1889) were supplemented from time to time with further prototypes for use by new signatories to the Metre Convention.

The preamble to the Metre Convention read "Desiring the international uniformity and precision in standards of weight and measure, have resolved to conclude a convention ...".

It issues an Annual Report on the administrative and financial position of the BIPM to the governments of the Member States of the Metre Convention.

These standards can vary widely, but are often mandated by governments, agencies, and treaties such as the International Organization for Standardization, the Metre Convention, or the FDA.

The Metre Convention was signed on 20 May 1875 and further formalized the metric system (a predecessor to the SI), quickly leading to the production of the IPK.

The desire for international cooperation in metrology led to the signing in 1875 of the Metre Convention, a treaty that established three international organisations to oversee the keeping of metric standards:

Initially the brochure was only in French - the official language of the metre convention, but recent versions have been published simultaneously in both English and French with French text being the official text.

In 1948 the CGPM commissioned the CIPM to "to make recommendations for a single practical system of units of measurement, suitable for adoption by all countries adhering to the Metre Convention".

In 1875, the United States solidified its commitment to the development of the internationally recognized metric system by becoming one of the original seventeen signatory nations to the Metre Convention or the Treaty of the Metre.

Currently there are over 200 atomic clocks in over 50 national laboratories around the world and the BIPM, in terms of the mandate given to it under the Metre Convention coordinates the various atomic clocks.

The Metre Convention established the International Bureau of Weights and Measures (Bureau international des poids et mesures, BIPM) in Sèvres, France, to provide standards of measurement for worldwide use.

BIPM operates under authority of the Metre Convention, a diplomatic treaty between fifty-one nations, the Member States of the Convention, through a series of Consultative Committees, whose members are the respective national metrology laboratories.

By 1870 the metric system had been adopted by most of the countries of Europe and on 20 May 1875 an international treaty known as the Convention du Mètre (Metre Convention) was signed by 17 to harmonise measurements between the states.

A series of conferences in France between 1870 and 1875 led to the signing of the Metre Convention and to the permanent establishment of the International Bureau of Weights and Measures, abbreviated BIPM after the French name.

Although there was debate in Australia's first Parliament after federation to consider adopting the metric system, metric units first became legal for use in Australia in 1947 when Australia signed the Metre Convention (or Convention du Mètre).
