Length Converter
The Length Converter instantly converts between metric and imperial length units, including millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles. It's commonly used for tasks like converting furniture or room dimensions from a US retailer's inches to metric ahead of an international move, or checking a recipe or DIY project's measurements against a tape measure marked in the other system. Conversion factors are fixed, internationally defined constants, so results are exact aside from standard decimal rounding in the display.
How This Tool Works
Enter a value and choose your source and target length units for an instant conversion.
Formula & Method
All units convert through meters as a common base, e.g., 1 foot = 0.3048 meters, 1 inch = 0.0254 meters.
Example Calculation
6 feet converts to about 1.83 meters, or 72 inches. A 10-kilometer race distance converts to about 6.21 miles, or roughly 32,808 feet — handy for comparing race distances listed in different countries. A 5K comes out to about 3.11 miles, just over the "5K = 3 miles" rule of thumb runners often use.
Frequently Asked Questions
How many centimeters are in an inch?+
One inch equals exactly 2.54 centimeters.
How many feet are in a meter?+
One meter equals approximately 3.281 feet.
Is this converter precise enough for construction?+
Yes, conversions use standard, internationally recognized conversion factors accurate to several decimal places.
Can I convert nautical miles or other specialized length units?+
This converter covers the most commonly used metric and imperial units, from millimeters through miles. For less common units like nautical miles (1 nautical mile = 1.852 km) or fathoms, you'd need a specialized converter, though you can still use meters or kilometers here as an intermediate step.
Why do some other sites give a slightly different conversion result?+
Small discrepancies usually come from rounding — some tools round intermediate values or use approximate factors, like treating 1 mile as 1.6 km instead of the exact 1.609344 km. This calculator uses precise, standard conversion factors throughout, so results match official definitions to several decimal places.
