<<<<That's very unscientific definition of metric system and makes no sense in reality.>>>> In actual fact, the metre has no relationship to any physical thing. It arose as a 'standard' measurement in 1791 after the French revolution when King Louis XVII instructed the French Academy of Sciences to define a standard metre. They decided that it should be One ten-millionth of the distance from the North Pole to the Equator measured on a line which passed through Paris. Unfortunately, even though the best minds in Paris at the time spent about four years working on this, they failed to allow for the flattening of the earth near the poles and so got the measurement wrong. At about the same time both the UK and the US were also proposing a change to metric measurements and Thomas Jefferson made a report to Congress on 4the July 1790 with such proposals. If this had been accepted, the standard measures would have been:- "Let the foot be divided into 10 inches; The inch into 10 lines; The line into 10 points; Let 10 feet make a decad; 10 decads one rood; 10 roods a furlong; 10 furlongs a mile.
