Explanation:
The value of all conversion factors that are used in dimensional analysis must be 1.
Dimensional analysis is a beautiful and systematic way of converting one unit to another using a simple scientific method in which a conversion factor of 1 is used to multiply the number to be converted.
For example, let us convert 1200kg to g:
We know that;
1000g = 1kg
The conversion factor is;
The above value is the same as 1 since 1kg and 1000g are the same.
Now multiply with 1200kg;
1200kg x = 1200000g
