The formulas for conversion are represented below:

in = cm / 2,54

Example: 30 Centimeters in Inches:

in = cm / 2,54

in = 30 / 2,54

in = 11,81

cm = in * 2,54

Example: 50 Inches in Centimeters:

cm = in * 2,54

cm = 50 * 2,54

cm = 127

Considering that 1 Centimeter is equivalent to 0.3937 Inches, you can use a rule of three to obtain that **100 Centimeters equal approximately 39.37 Inches**.

1 cm - 0,3937 in

100 cm - x

Apply the rule of three and get:

x ~~cm~~ = 100 x 0,3937 in~~cm~~

x = 39,37 in

If every 1 Inch we have 2.54 Centimeters, just multiply the number of Inches (100) by 2.54, so you will get that **100 in are equivalent to 254 cm**. Observe the calculation below:

cm = in * 2,54

cm = 100 * 2,54

cm = 254
