Definition of Kilometer

A kilometer (km) is a metric unit of length equal to 1,000 meters (or approximately 0.621371 miles). This unit is the standard for measuring:

  • Road distances and highway markers in most countries
  • Geographic distances on maps and in navigation
  • Running and cycling routes in sports and fitness
  • Weather systems and visibility ranges
  • Municipal planning and urban development
Kilometers are used officially for expressing distances between geographical places on land in most of the world, with notable exceptions being the United States and the United Kingdom, where miles are still commonly used. The kilometer was first introduced as part of the metric system during the French Revolution and has since become the global standard for measuring medium to long distances.

Definition of Inch

An inch (in) is a fundamental unit of length in both the United States customary system and the British imperial system of measurement. Precisely defined as exactly 25.4 millimeters since 1959, the inch has a rich history dating back to ancient measurements based on the human body. One inch was traditionally represented by three barleycorns placed end to end. In modern usage, inches are predominantly used in the United States, Canada, and the United Kingdom for various applications including:

  • Screen and display sizes (televisions, monitors, smartphones)
  • Construction materials and hardware
  • Plumbing fixtures and pipe diameters
  • Tire dimensions
  • Paper sizes (such as 8.5 × 11 inches)
The inch is commonly divided into fractions (halves, quarters, eighths, sixteenths) in construction and engineering, or decimals in technical applications.
