Length is one of the most fundamental physical quantities, measuring the distance between two points in space. Whether you're measuring the height of a building, the distance of a marathon, or the size of a microchip, accurate length conversion is essential. Our length converter supports both metric units (based on the meter) and imperial units (based on the foot and inch), allowing seamless conversion between systems used around the world.
The quest for standardized length measurement spans millennia. Ancient civilizations used body parts as references—the cubit (forearm length), foot, and hand span. The metric system emerged from the French Revolution in 1795, with the meter defined as one ten-millionth of the Earth's quadrant. Today, the meter is defined by the speed of light, providing unprecedented accuracy. The imperial system evolved from English units, with the inch officially standardized in 1959 as exactly 25.4 millimeters.
Multiply the length in meters by 3.28084 to get the equivalent in feet.
Example: 5 meters × 3.28084 = 16.4042 feet
Multiply the length in feet by 0.3048 to get the equivalent in meters.
Example: 10 feet × 0.3048 = 3.048 meters
Multiply the distance in miles by 1.60934 to get kilometers.
Example: 26.2 miles × 1.60934 = 42.16 kilometers (marathon distance)
Multiply inches by exactly 2.54 to get centimeters (this is an exact definition).
Example: 12 inches × 2.54 = 30.48 centimeters
A marathon race covers exactly 42.195 kilometers, which originated from the Greek legend of Pheidippides.
NBA regulation basketball hoops are mounted at a height of 10 feet from the floor.
The global average adult human height is approximately 170 centimeters.
An American football field (including end zones) is 120 yards or 360 feet long.
The world's highest peak stands at 8,849 meters above sea level.
A typical smartphone screen diagonal measures about 6.5 inches.
