In the U S A the system of weights and measured first adopted was
that of the English, though a few differences came in
when decisions were made at the time of standardization in 1836.
For instance, the wine-gallon of 231 cubic inches was used
instead of the English one (as defined in 1824) of about 277 cubic
inches. The U S A also took as their standard of dry
measure the old Winchester bushel of 2150.42 cubic inches, which
gave a dry gallon of nearly 269 cubic inches.
Even as late as the middle of the 20th century there were some
differences in UK and US measures which were nominally the
same. The UK inch measured 2.53998 cm while the US inch was
2.540005 cm. Both were standardized at 2.54 cm in July
1959, though the U S continued to use 'their' value for several
years in land surveying work - this too is slowly being
metricated.

Le Systeme international d’Unites was adopted by nearly every
country in the world in October 1960. It is based upon 7 fundamental
units. We will look at 3 of them, 2 of which are metric units. They are:
the meter (the distance light travels, in a vacuum, in 1/299792458
of a second), the kilogram (the mass of an international prototype in
the form of a platinum-iridium cylinder kept at Sevres in France), and
the Kelvin (1/273.16 of the thermodynamic temperature of the triple
point of water).
Here are some common
prefixes used in the
metric system. 
