Physical quantities are like the alphabets of the physics language.We try to understand the physics in terms of the physical quantities. To measure this physical quantities we have units and to identify the content of them,we are having dimensional formulas.
The unit of a physical quantity can be expressed in different systems of units.Though numerical value appears like different m in different system of units,the actual values are same.Dimensional formula is a representation of the physical quantity in terms of the fundamental quantities.In measuring this physical quantities we always get possible errors and we had to deal them using approximations also.
Following are the topics of units, dimensions errors under approximations in measurements that are listed in this blog.
