Question

Convert 34.0 mm to inches. Please use dimensional analysis, I know the answer is 1.34in I just don’t know how to get there.

Answer 1

$34.0mm\ x\ \frac{cm}{10mm}\ x\ \frac{in}{2.54cm}$

put your equation so that your units cancel. The 'mm' will cancel with each other which will get you 'cm' and then the 'cm' will cancel with each other which will get you 'in'.
