Hi crenshad-ga, and thanks for your question.

Centimeters (cm) are a linear measure of distance.  Square centimeters
are a measure of area.  For example, a 2cm x 3cm rectangle would have
an area of 6 cm^2 (square centimeters).

This being said, there are 2.54 cm per inch.  To convert cm to inches,
divide by 2.54.

This gives 31cm = 12.2 inches.

Note that you can use Google to convert between units.  In this case,
you would simply type 31cm = ?in in the Google search box, and Google
will return the result.

You do, however, have to make sure that the units on both sides of the
equals sign are measures of the same sort of quantity (e.g., Length,
Area, Volume, energy, time, mass, force, power, etc.)  For example,
Google would not know how to convert 31cm into units of square inches
because the centimeter is a unit of length while square inches is a
unit of area.
