How to convert centimeter to inch
Centimeter (cm) and Inch (in) both measure length. Whether you are studying, traveling, cooking, or working on a project, converting between them should be fast and accurate.
This page converts centimeter to inch — the direction you need when a product, map, or recipe uses metric but you think in US or UK customary units.
The standard relationship used on this page means that 1 centimeter equals 0.393700 in. Enter any number in the calculator — use the swap button to reverse the direction without leaving the page.
For example, 10 cm is about 3.937007 inches — handy when a product lists metric dimensions but you think in inches (TVs, monitors, paper sizes).

When you'll use this
- Checking a TV or monitor spec sheet that lists panel width/height in cm against the inch size printed on the box
- Buying furniture from a European retailer (IKEA, Made.com) and fitting it into a US room measured in feet and inches
- Comparing phone or tablet dimensions listed in cm on an international spec page
- Converting a paper size (A4 is 21 × 29.7 cm) to the closest US Letter equivalent in inches
- Reading a European clothing or shoe size chart that gives foot length in cm
Practical note
A common trigger for this exact page is TV shopping: a European retailer lists a panel as "140 cm," while every US site advertises the same model as "55-inch." Punching 140 into this converter returns about 55.1 inches, confirming it is the same television. The same pattern shows up with monitor panels (a "27-inch" monitor is roughly 68.6 cm diagonal), passport photo booths that print dimensions in cm, and IKEA furniture listings that give shelf depth in centimeters when you are used to thinking in inches for US closets and bookshelves. Because the cm-to-inch factor is an exact legal definition, there is zero rounding error to worry about — the only rounding happens in how many decimal places you choose to display.
Tips
- 1 inch is defined as exactly 2.54 cm, so this conversion is exact — not a rounded approximation like some unit pairs.
- For tape-measure work, round to the nearest 1/8 inch (0.125 in) since US rulers and tape measures mark eighths, not decimals.
- Screen sizes are measured diagonally, not by width or height — a "55-inch" TV has a 55 in diagonal, not a 55 in width.
