CM to Inches Converter — Free & Instant

What This Tool Does

This tool converts any length in centimetres to inches using the exact conversion factor (1 cm = 0.393701 inches), not a rounded approximation. It's built for the most common everyday reasons this comes up: checking height against a US or UK reference, buying furniture or a TV listed in inches, or reading a clothing or shoe measurement from an international size chart.

How to Use It

Type your length in centimetres into the value field (the tool is pre-set to convert CM → Inches).
Press Convert.
Your result in inches appears instantly. Need a different unit pair? The Category, From and To dropdowns above the result still work if you want to switch.

Example

A height of 170 cm — a common reference height in India — converts to 66.93 inches, or 5 feet 7 inches, which is how the same height would usually be described on a US visa form or an international dating profile.

Frequently Asked Questions

How many inches is 1 cm, exactly?

1 centimetre equals exactly 0.393701 inches. For a fast mental estimate, dividing centimetres by 2.5 gets you close enough for most everyday purposes.

Why do TV and laptop screens get measured in inches everywhere, even in India?

Screen sizes are measured diagonally in inches as a long-standing global manufacturing convention, regardless of which measurement system a country otherwise uses day-to-day — so a "55-inch TV" means the same physical size whether you're in Mumbai or Manchester.

Is this accurate enough for clothing or shoe size conversions?

Yes for raw length — but remember that clothing and shoe "sizes" (like UK size 8 or US size 10) are separate numbering systems, not direct unit conversions, so always check a proper size chart in addition to converting the raw centimetre measurement.
