The international system of units is also known as SI units. It was introduced to remove the confusion between many units. According to standard international form, the SI units of various quantities are listed below:
Mass = kg
Length = m
Time = s
Force = N
To obtain the SI units of the following dimensions, they must be converted to universal standard by expressing them by the given relations:
mm-mN = ×10-3 * x10-3 = 1 x10-6 N.m
mg/mm = ×106 kg /10-3m = 1×109 kgm-1
km/ms = ×103 m /x10-3 s = 1×106 ms-1
kN/(mm)2 = ×103 / ×10-3 = 1×106 Nm-2
