Who invented the metric system?

antoine-laurent de lavoisier, of course, who is also considered the father of modern chemistry.\ndue to his prominence in the french government, he was beheaded by revolutionists later... shame, really

Why aren't you Americans using metric yet?\nDrag yourself into last century already!

John Harrison developed longitude.\n\nLatitude is a bit more difficult to determine and is mostly about mathematics but I believe mathematician Karl Gauss had something to do with it. But you should research that some more.

D) 5.9cm \n\n10 mm = 1 cm\n\nThis is why the metric system is so much easier than the english system.\n\njust think about all of the wasted brain power trying to figure inches feet miles etc...

We invented the concept of pi before the Greeks. Using higher math, we were able to create a perfect circle in three dimensions. Scultping the columns only required a complex circular leveling device using water which we invented in the 8th dynasty.

Euclid.\nGreek geometer who wrote the Elements , the world's most definitive text on geometry. The book synthesized earlier knowledge about geometry, and was used for centuries in western Europe as a geometry textbook. The text began with definitions, postulates ("Euclid's postulates "), and common opinions, then proceeded to obtain results by rigorous geometric proof. Euclid also proved what is generally known as Euclid's second theorem:  the number of primes  is infinite.  The beautiful proof Euclid gave of this theorem is still a gem and is generally acknowledged to be one of the "classic" proofs of all times in terms of its conciseness and clarity. In the Elements , Euclid used the method of exhaustion and reductio ad absurdum. He also discussed the so-called Euclidean algorithm  for finding the greatest common divisor  of two numbers, and is credited with the well-known proof of the Pythagorean theorem. \nNeither the year nor place of his birth have been established, nor the circumstances of his death, although he is known to have lived and worked in Alexandria for much of his life. In addition, no bust which can be verified to be his likeness is known (Tietze 1965, p. 8).

I think it is Albert Einstein... Einstein stated The Theory of Relativity, breaking down Isaac Newton's The laws of Three Motions and Theory of Gravitation, demonstrated that Newton's theories were only partially right. What is more, scientists believe that there will need more than 200 years for another "Einstein" be born in this world to help the innovation of Physics. Current Mathematics is not adequate for solving Physical problems any more.

It it considered that the first proposal of using symboll "pi"  as the ratio of the circumference of a circle to its diameter was firstly appeared in the works of William Jones. But he was  a Welsh mathematician, not Swiss.\n\nFrom section "History of the notation" of first attached wiki article:\nThe symbol "π" for Archimedes' constant was first introduced in 1706 by William Jones when he published A New Introduction to Mathematics, although the same symbol had been used earlier to indicate the circumference of a circle. The notation became standard after it was adopted by Leonhard Euler.

aryabhatta of india,he also discoved the decimal system-he was a great scientist of his time,most others would say arabs,but they don't know thay arysbhatta taught them.u know that there r 2 numeral systems-roman numerals and arab numerals but u would be surprised that it is actually india who invented the arab system,arabs r given the credit because they taught all our information to europe but said that they invented this system.

some background:\n1866\n    The use of the metric system made legal (but not mandatory) in the United States by the (Kasson) Metric Act of 1866 (Public Law 39-183). This law also made it unlawful to refuse to trade or deal in metric quantities.\n1893\n    ..... metric prototypes were declared "fundamental standards of length and mass" in the Mendenhall Order. Since that date, the yard, pound, etc. have been officially defined in terms of the metric system.\n\nThis timeline, and more, can be found at http://lamar.colostate.edu/~hillger/dates.htm\n\nOur common units of miles, pounds and degrees fahrenheit are defined metricly. But still it's not how we in the U.S. think.\n\nWikipedia says:\n"Only France, the United States, the United Kingdom, and Japan have seen significant popular opposition to metrication, the main objections being based on tradition, aesthetics, economical impact and distaste for measures viewed as foreign."\n\nIt's the imp of the perverse.

This question is miscategorized.\n\nSpecial Education refers to the education and parenting of children with special needs.\n\nThat being said... the metric system (e.g. kilograms, meters, etc.) was introduced by Napoleon Bonaparte in the early 1800's, because he wanted a standard set of weights and measures throughout his empire.\n\nThe English system (lbs, oz, inches, etc.) evolved during the Middle Ages based on common items used for measuring. For instance, the "inch" was originally based on the practice of using from the tip to the first joint of the thumb as a measure for small items.

The metric system is based on multiplies of 10 and matematically is easier to divide or multiply by 10 than other convertion factors. Actually the ethimology of the words indicate the factor that have been applied to an unit (eg: on "centimeter", the prefix "centi" means 100, then centimeter means a hundredth of a meter or 0.01m)\n\nQuote: "The meter was originally defined as one ten-millionth (0.0000001 or 10-7) of the distance, as measured over the earth's surface in a great circle passing through Paris, France, from the geographic north pole to the equator. "\n\nNowadays, the meter, the gram and other units are defined using systems that are independent of the geography (eg: 1 meter is the distance traveled by a ray of electromagnetic (EM) energy through a vacuum in 1/299,792,458 (3.33564095 x 10-9) of a second).\n\n\nI hope you find this helpful,\n\nSincerely,\n\nManuel-(block)-Cachilapex
