The origins of the metric system date back to the sixteenth century when, Simon Stevin published details of his decimal notation, and the seventeenth century when John Wilkins published a proposal for a decimal system of measurement based on natural units. The first practical realisation of the metric system came during the French Revolution, when the existing system of measure which had fallen into disrepute was replaced by a decimal system based on the kilogram and the metre. The metric system was, in the words of philosopher and mathematician Condorcet, "for all people for all time". The unit of length, the metre, was based on the dimensions of the Earth, and the unit of mass, the kilogram, was based on the mass of water having a volume of one litre or one thousandth of a cubic metre. Reference copies for both units were manufactured and placed in the custody of the French Academy of Sciences.
During the first half of the nineteenth century, the metric system was adopted by the scientific community. In the middle of the century, James Clerk Maxwell put forward the concept of a coherent system where a small number of units of measure were defined as base units, and all other units of measure, called derived units, were defined in terms of the base units. Maxwell proposed three base units - length, mass and time. This concept worked well with mechanics, but attempts to describe electromagnetic forces in terms of these units were beset with difficulties. By the end of the nineteenth century, four principal variants of the metric system were in place for the measurement of electromagnetic phenomena, three based on the centimetre-gram-second system of units(CGS system), and one on the metre-kilogram-second system of units (MKS system). This impasse was resolved by Giovanni Giorgi, who in 1901 proved that a coherent system that incorporated electromagnetic units had to have an electromagnetic unit as the fourth base unit.
Until 1875, the French government owned the prototype metre and kilogram, but in that year the Convention of the metre was signed, and control of the standards relating to mass and length passed to a trio of inter-governmental organisations, the senior of which was the General Conference on Weights and Measures (in French the Conférence générale des poids et mesures or CGPM). During the first half of the twentieth century, the CGPM cooperated with a number of other organisations, and by 1960 it had responsibility for defining temporal, electrical, thermal, molecular and luminar measurements, while other international organisations continued their roles in how these units of measurement were used.
In 1960, the CGPM launched the International System of Units(in French the Système international d'unités or SI) which had six base units, the metre, kilogram, second, ampere, degree kelvin (subsequently renamed the "kelvin") and candela, and 22 derived units. The mole was added as a seventh base unit in 1971. During this period, the metre was redefined in terms of the wavelength of the waves from a particular light source, and the second was defined in terms of the frequency of radiation from another light source. By the end of the century, work was well under way to redefine the ampere, kilogram, mole and kelvin in terms of the basic constants of physics, thereby ensuring that all the base units were in theory available to everybody. It is expected that this work will be completed by 2014.
The metric system was first developed in France during the French Revolution in the late 18th century. It was officially adopted as the global standard of measurement by the General Conference on Weights and Measures in 1960.
The metric system was first used in France during the 18th century.
The metric system was first developed in France just before and just after the revolution in the 1780s and 90s.

Which county first converted to the metric system?
France. They like to call it System Internationale d'Units. Ironically, it was the United States, the only major country NOT using the Metric System, which first proposed it, or something very like it. Apparently we got distracted by something and the French grabbed the ball and ran with it, so to speak.
Did the development of the metric system first began in 1960?
the SI was replaced because the metric system was more accurate and percise.
When did the us first oppose the metric system?
The U.S. first opposed the metric system in the 19th century when Congress passed the Metric Act of 1866, which allowed but did not require the use of the metric system. Since then, the U.S. has been slow to fully adopt the metric system for everyday use, despite efforts to encourage its use in certain industries.
When and where was the metric system first used?
The earliest known standardised system of linear measurement is the Egyptian Royal Cubit, which is known to have been accurately enforced from at least the time of the pharaoh Djoser in 2,700 B.C.
What country calculated the meter?
France calculated the meter. The meter was first defined as one ten-millionth of the distance from the equator to the North Pole, through Paris. This definition was adopted by the French Academy of Sciences in 1791.
What country used the meter first?
France invented the metric system
What country developed the first factory system?
ENGLAND
What country developed SI system?
It was first adopted by France.
Which country first developed hydroelectricity?
which is the first country developed hydroelectricity
Who was the person to first suggest the use of a metric system?
A few philosophers and scientists had proposed a decimal system earlier, but in 1790 the National Assembly of France asked the French Academy of Sciences to invent a standard system of weights and measures. The system they developed became the metric system and it was adopted by the French government in 1795.
Who used metric measures first?
France originated the metric system.
What country developed the first zeppelin?
Germany developed the first Zeppelin
Where was the plantation system first developed?
The plantation system was first developed by Portuguese explorers in West Africa.

Is Taiwan a developed country?
Yes, it is a developed country. For those that don't agree that it is a "country" then developed or first world area would do.
