Mathematics has always stood as the tool for the precision & accuracy of a human being no matter what exactly the dimension is, but if anybody wants to prove his logic then he must have to rely over mathematics. This is because a one metre scale has a length of one metre & there is no controversies involved as it is specified by the international board of units & measurements that 100 cms is equal to one metre, the conversion of an inch into centimeters i.e. one inch is equal to 2.54 cms &, the conversion of one feet into inches & there by calculating a feet to metre conversion is a lame man calculation. Mathematics has been the preferred language of scientists as it put them on a better to explain themselves to the other ignorant people for the purpose of achieving a common goal towards community welfare which would have been impossible in the absence of the data with a measurement scale. Mathematics is the language of physics, the branch of science which deals with the basic laws of nature in scientific terms providing the base for any concept under consideration. In the absence of acute measurements the world would not have appeared as it is seen today. As for example if the distance in light year would have taken in kilometers then the astronaut would have lost in the universe & may be the life span of a man would not have been sufficient to reach alpha centauri; if the scale of measurement been inaccurate.

We use to calculate the risk before our investments but what if a million dollars project being under estimated as probably one lakh dollars. First of all our world would not have been possible if units of measurement were absent. Simply in previous days before Galileo & Columbus sailed across the sea, people believed that they will fell down of the earth if they will reach the horizon of sky meeting the sea by standing at the shore. Medical science would not have developed if Benjamin Franklin was not there to explain the anatomy of human body. But whatever knowledge we gain, the most important task out of it is of ‘integration'. Its only after the integration of knowledge that a complete cycle is framed in the form of a chain. This integration is possible through means of the conversion rules like the feet to metre conversion as for example; similarly there are many conversions like conversions in terms of temperature, currency, weight, length, area, volume, etc. hence we are required to have a flexible structure of units & measurements which should allow us to have a greater freedom in terms of precision & data accuracy.
