Length Converter
Convert between common length units: meters, kilometers, feet, inches, miles, yards, and centimeters. Enter a value and choose the source unit; all other units update instantly. Conversions use standard definitions (e.g. 1 m = 100 cm, 1 in = 25.4 mm).
Convert length
Enter value and choose unit to convert.
How it works
All values are converted to meters first, then to the target units. Factors: 1 km = 1000 m, 1 cm = 0.01 m, 1 ft = 0.3048 m, 1 in = 0.0254 m, 1 mi = 1609.344 m, 1 yd = 0.9144 m. The result shows the same length in every listed unit.
Example: 1 meter = 100 cm = 3.28084 ft = 39.37 in (approximately).
When to use it
Use it for recipes, travel, construction, or any task where you need to switch between metric and imperial or between different length scales quickly.
