Transform measurements between meters, feet, inches, kilometers, and miles in seconds. Get precise conversions with our free length converter app.
A length converter transforms measurements from one unit to another. You enter a value in meters, feet, inches, kilometers, or miles, and the tool gives you the equivalent in your target unit. This unit converter length tool saves time and eliminates manual calculation errors.
Every day, people worldwide need to compare distances, heights, and dimensions across different measurement systems. The metric system dominates most countries, while the United States relies on imperial units. Scientists use meters and kilometers, builders work with feet and inches, and travelers switch between both systems depending on location.
Our length converter app uses precise conversion factors to translate your measurements. Type your number, select your starting unit and desired unit, and get instant results. The tool handles everything from nanometers to nautical miles.
You get results accurate to eight decimal places. The converter multiplies your input by the exact conversion factor between units. For example, when you convert meters to feet, the tool multiplies your value by 3.28084. When you convert the given lengths from derived units to meters, the process reverses.
Construction workers need this length to feet converter when reading blueprints. International students convert measurements for science classes. Online shoppers check if furniture dimensions fit their rooms. Travelers calculate driving distances in unfamiliar units. Athletes track running distances in both kilometers and miles.
Engineers switch between metric and imperial specifications daily. Machinists verify part dimensions. Architects scale drawings. Real estate professionals describe property measurements. Pilots and sailors use nautical miles alongside standard units.
The metric system builds on the meter as its foundation. All other metric length units multiply or divide meters by powers of ten. This logical structure makes mental calculations easier.
The system originated in France during the 1790s. Scientists wanted a universal standard based on natural constants. They defined the meter as one ten-millionth of the distance from the equator to the North Pole. Modern definitions use the speed of light for even greater precision.
Imperial measurements evolved from body parts and everyday objects. A foot represented the length of a human foot. An inch matched the width of a thumb. A yard equaled the distance from nose to fingertip.
These units lack the decimal simplicity of metric measurements. Converting between imperial units requires memorizing specific ratios. A mile contains 1,760 yards or 5,280 feet or 63,360 inches. These irregular numbers make calculations harder without a converter.
Learn these approximations for fast estimates when you lack a calculator:
Round these numbers when precision matters less. For driving distances, saying "100 kilometers equals 60 miles" works fine. For construction, use the exact values from our length converter app.
Converting lengths follows a straightforward mathematical pattern. You multiply your starting value by a fixed conversion factor. Different unit pairs need different factors.
Basic Formula: Result = Input Value × Conversion Factor
The conversion factor from meters to feet equals 3.28084. Multiply any meter measurement by this number to get feet.
Example 1: Convert 5 Meters to Feet
5 meters × 3.28084 = 16.4042 feet
Five meters stretches about 16 feet and 5 inches.
Example 2: Convert 2.5 Meters to Feet
2.5 meters × 3.28084 = 8.2021 feet
Two and a half meters equals roughly 8 feet and 2 inches.
One mile equals 1.60934 kilometers. This conversion helps travelers understand road signs in metric countries.
Example 1: Convert 10 Miles to Kilometers
10 miles × 1.60934 = 16.0934 kilometers
A 10-mile drive equals about 16 kilometers.
Example 2: Convert 100 Miles to Kilometers
100 miles × 1.60934 = 160.934 kilometers
Highway distances scale proportionally.
The inch to centimeter factor equals exactly 2.54. This standardized ratio dates to 1959.
Example 1: Convert 12 Inches to Centimeters
12 inches × 2.54 = 30.48 centimeters
One foot equals 30.48 centimeters.
Example 2: Convert 6 Inches to Centimeters
6 inches × 2.54 = 15.24 centimeters
Half a foot equals about 15 centimeters.
