Length Converter
Convert length units: meters, feet, kilometers, miles, inches and more.
Length and distance conversions are needed constantly in construction, travel, science, and everyday measurement. This converter handles all major length units — metric (mm, cm, m, km), imperial (inch, foot, yard, mile), nautical (nautical mile, fathom), and traditional Indian units (gaz, hath, kos). It also shows all conversions simultaneously so you can see the full picture at once.

For scientific use, the converter also handles micrometres (microns), nanometres, and angstroms for precision measurement contexts.
💡 Key Facts & Information
Key conversions: 1 metre = 100 cm = 3.281 feet = 1.094 yards = 39.37 inches. 1 kilometre = 1,000 m = 0.621 miles = 1,094 yards. 1 foot = 12 inches = 30.48 cm. 1 mile = 1.609 km = 5,280 feet. 1 nautical mile = 1.852 km (used in aviation and maritime).
