What is the value of all conversion factors that are used in dimensional analysis?

Fittoniya [83]

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.
