How to Convert Length Units
Our length converter makes it easy to convert between different units of length and distance. Whether you're working with metric units like meters and kilometers or imperial units like feet and miles, get instant, accurate conversions.
Understanding Length Units
Length is a measure of distance from one point to another. The metric system uses meters as the base unit, while the imperial system uses feet. Different situations call for different units-kilometers for road distances, centimeters for measurements, inches for screen sizes.
Common Length Conversions
Length conversions use fixed ratios. Key relationships: 1 inch = 2.54 cm, 1 foot = 12 inches = 30.48 cm, 1 mile = 1.609 km, 1 meter = 100 cm = 3.281 feet.
Example:
To convert 5 feet to meters: 5 × 0.3048 = 1.524 meters. To convert 100 cm to inches: 100 ÷ 2.54 = 39.37 inches.
