Unity in the metric system.

- Abstract
The article examines the perfection of the metric system as a scientifically devised basis for weights and measures. The units of length, mass and time are considered as fundamental in any system of measurement. Other units are derived from them. The meter which is the unit of length was originally intended to be one ten millionth part of the earth's quadrature. The mass of one liter of water at 4 degree centigrade determines the unit of mass. For any system of measurement, volume is length cubed, velocity is length divided by time and acceleration is length divided by time squared. Complicated units thus can be reduced to the three fundamentals of which two bear a unit relationship. The varied possibilities of the unit system of measurement triggers interest among students. The metric system has been described as a unit system where mass and time may be derived from length.
