Answer 1

One in is equal to 2.54 cm, then we can do the following:

$14.3cm\cdot\frac{1\text{ in}}{2.54\operatorname{cm}}$

The centimeter units cancel out and we have:

$\frac{14.3\text{ in}}{2.54}=\text{ }5.629921\text{ inches}$

14.3 cm = 5.629921 Inches

Rounded to 4 decimal places: 14.3 cm = 5.6299 Inches
