Although the metric system had been in use for many years in many different countries it still lacked complete standardization among its users
Therefore an attempt was made to modernize and standardize the metric system
The result was the system international unit known as si or the international metric system
The basic unit of length in si is the meter or meter (in the common international spelling)
The si meter is defined by a physical standard that can be reproduced anywhere with unvarying accurac standard that can be reproduced anywhere with unvarying accuracy
1 meter = the length of the path traveled by light in a vacuum during a time interval of 1/299,792,458 of a second
Probably the primary advantage of the metric system is that of convenience in computation
All subdivisions and multiples use 10 as divisor or multiplier as be seen in the following table
