What Is an Inch and What Is a Foot?

An inch is a unit of length commonly written as in or with the double-prime symbol ″. A foot is written as ft or with the prime symbol ′. Both units are used in the US customary and imperial measurement systems.

The relationship is exact: 1 foot = 12 inches, and 1 inch = 1/12 foot.

Common Conversion Mistakes

  • Dividing by 10: A foot contains 12 inches, not 10.
  • Confusing decimal feet with feet and inches: 5.5 feet equals 5 feet 6 inches, not 5 feet 5 inches.
  • Rounding too early: Keep the full value during the calculation and round only the displayed result.
  • Mixing symbols: Use in or ″ for inches and ft or ′ for feet.

How to Verify the Answer

Multiply the calculated feet by 12. The result should return the original number of inches.

Example: 3 feet × 12 = 36 inches

For a feet-and-inches result, multiply the whole feet by 12 and add the remaining inches: 5 × 12 + 11 = 71 inches.
