Definition of Foot

A foot (ft) is a unit of length in the imperial and US customary systems, defined exactly as 0.3048 meters. This fundamental unit has historical origins in human anatomy, originally based on the length of an adult human foot. Today, the foot is a crucial measurement unit in:

  • Architecture and construction (building heights, room dimensions)
  • Aviation (altitude measurements)
  • Land surveying and property descriptions
  • Interior design and space planning
  • Sports field dimensions (football, soccer)
One foot equals 12 inches, and three feet make one yard. In construction, feet are often expressed in decimal form or in feet and inches (e.g., 5' 6"). The foot remains the standard unit for building construction in the United States and is widely used in the United Kingdom despite metric adoption.

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.
