Length unit conversion changes the same length from one measurement unit to another, such as kilometers to meters, meters to feet or miles to kilometers. The tool supports quick conversion between metric, imperial, Chinese and some astronomical-scale units.
Supported units include kilometers, meters, decimeters, centimeters, millimeters, micrometers, nanometers, picometers, angstroms, inches, feet, yards, miles, nautical miles, Chinese li, zhang, chi, cun, mils, typographic points, light-years, astronomical units and parsecs.
Enter the value, select the source and target units, and the system automatically calculates the result. The quick reference table can also use the current source unit as a basis to display corresponding values in other common units.
1 kilometer equals 1000 meters, or 1 km = 1000 m. 1 mile equals 1.609344 kilometers, and 1 foot equals 0.3048 meters.
Length conversion can be used for engineering measurement, architectural design, machining, map measurement, international logistics, daily life and study. Conversion between Chinese and imperial units and metric units is particularly useful for cross-region data verification.
