Length Conversions

Length and distance conversions bridge the gap between the metric system (meters, kilometers, centimeters) and the imperial system (miles, feet, inches). Most countries use metric for science, construction, and daily life, while the United States primarily uses imperial. Accurate length conversion is essential for international travel, engineering specifications, clothing sizes, and reading foreign road signs.

  • ✓Converting km to miles for US road trips, GPS settings, and running distances
  • ✓Converting cm to inches for clothing sizes, screen dimensions, and furniture
  • ✓Converting feet to meters for architecture and international construction
  • ✓Converting meters to feet for altitude readings and swimming pool depths

Frequently Asked Questions — Length

How many feet are in a meter?
1 meter equals 3.28084 feet. To convert meters to feet, multiply the meter value by 3.28084. Conversely, 1 foot equals 0.3048 meters.
How many kilometers are in a mile?
1 mile equals 1.60934 kilometers. To convert miles to kilometers, multiply by 1.60934. To convert km to miles, multiply by 0.62137.
What is the difference between the metric and imperial systems for length?
The metric system uses meters as the base unit with decimal (base-10) prefixes: 1 km = 1,000 m, 1 m = 100 cm = 1,000 mm. The imperial system uses historical factors: 12 inches = 1 foot, 3 feet = 1 yard, 1,760 yards = 1 mile. Most countries use metric; the US uses imperial for everyday measurements.
