A person has a height of 65 inches You want to find out the height of
that person in centimeters. Which
unit conversion would you use?

1 inch = 2.54 centimeters

A conversion factor or unit conversion is used to change the units only without affecting the value.

1 inch = 2.54 centimeters

Given, height = 65 inches

So, the height of  that person in centimeters = 65 x 2.54

                                                                         = 165.1 cm    

Hence, the person's height in centimeters will be 165.1 cm.
