The
first steps of humanity have already presented the need of finding
units of measurement. The metres and weights were among the first
discoveries made by human. Human body itself constituted the basis
for the creation of the first metrical systems. Thus some of the
first units been created was the daktylos, palami, vrahiwn, poys,
step, etc. In cases of measurement of distances of big scale,
the units were constituted by the distance of stone shot, the
distance that covers in one day one pedestrian, the period of
the sun, of the moon etc. Depending on the circumstances similar
units is still used.
Despite the common root of most of metrical systems, these systems
differed from place to place. Thus we had the parallel growth
of many systems that rendered the transactions among populations
difficult, however the small number of them had not created the
need for finding of a world wide commonly acceptable metrical
system.
