Well you have to set up a fraction ratio

For example I want to convert 88 inches squared to mm not squared but just a length dimension

88 inches x 1 mm/ 0.0393 inches = 2,239.185750636132 so inches ^2 divided by inches will leave you with inches and millimetres which is incorrect the correct way using unit analysis is

square root of 88 is 9.38083151964686 now divide this by 1 mm/0.0393 inches and your only left with mm not inches and mm. Your end result in an equation will look as follows

9.38083151964686 inches X 1 mm/0.0393 = and I'll let you do that math 😃.

Just to answer possible questions you may ask where did 0.0393 come from well that is the amount of inches in a mm you may also ask why mm on top that is for unit analysis to cancel out the inch measurements leaving us with our desired mm

To recap we went from inches^2 square rooted it to make it inches so they cancel in our equation( Inch/inch ) and were left with mm
