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 incm
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
