How it works

Length converters move a measurement between metric and imperial units—meters, centimeters, millimeters, kilometers, inches, feet, yards, and miles.

Enter a length in one unit to see the equivalent in all others. Conversions use fixed international factors (for example, an inch is exactly 25.4 millimeters).

Common uses include DIY projects, fabric and lumber cuts, map scales, athletics, and science class problems that mix unit systems.

For human stature with feet and inches fields, prefer the Height Converter. For tiny engineering tolerances, verify significant figures beyond everyday rounding.

Large distances (miles vs kilometers) are the same math as small ones—only the unit scale changes.

Frequently asked questions

How many centimeters are in an inch?
Exactly 2.54 centimeters per inch by international definition. The converter uses that exact factor.
Is a US survey foot different?
Historically yes for some surveying contexts. Everyday Calcuit conversions use the international foot used in common consumer math.
Why is my tape measure in sixteenths?
Imperial fractional inches are traditional for construction. Convert to decimal inches or millimeters when you need calculator-friendly numbers.
Can I convert square or cubic units here?
No. This page is linear length only. Area and volume need squared or cubed conversions.
