How to use this tool

  1. Enter the length in centimetres.
  2. Read the result in inches. For height, divide the inches by 12 to get feet.

Formula and method

inches = centimetres ÷ 2.54

For height in feet and inches, divide the result by 12: the whole number is feet, the remainder is inches.

Worked examples

  2. 68.898 ÷ 12 = 5 feet, remainder 8.9

5 feet 8.9 inches.

A 68 cm television

  1. 68 ÷ 2.54 = 26.77

About 27 inches measured the same way.

Notes and limitations

  • Screen sizes are measured diagonally, so a '27 inch' monitor is 27 inches corner to corner, not across.
  • The 2.54 factor is exact by international definition.
  • Clothing and shoe sizes do not convert by length alone — sizing systems differ by more than the units.
