Answer» Conversion of units of physical quantities from one system to another system: The method of dimensional analysis can be used to obtain the value of the physical quantity in some other system when its value in one system is given. If a,b,c are the dimensions of a physical quantity in mass, length and time, then: Here M1 ,L1 ,T1 and M2 ,L2 ,T2 are the units of mass, length and time in the two systems, then The equation can be used to find out the value of a physical quantity in the second or the new system, when its value in first system is known. |
