Centimeters to Inches
A centimeter is one hundredth of a meter, commonly used for paper sizes and human height in metric countries. An inch is exactly 2.54 centimeters, used for screen sizes, paper formats, and everyday measurements in the US. 1 cm equals ≈0.393701 in, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to length, measured here against length's base unit (m) — every other length unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
in = cm × ≈0.393701
cm = in × 2.54
Worked example: 5 cm × ≈0.393701 = ≈1.9685 in.
