Formula and method

5 ft 6 in = 167.64 cm = 1.6764 m = 66 in. The compound feet/inches and meters/centimeters fields use colons. Enter 5:6 for five feet six inches; 5.6 decimal feet is a different length.

5 ft 6 in = 167.64 cm = 1.6764 m = 66 in

Assumptions and limitations

  • The compound feet/inches and meters/centimeters fields use colons. Enter 5:6 for five feet six inches; 5.6 decimal feet is a different length.
  • These are linear lengths, not areas or volumes. Square and cubic units require squared and cubed conversion factors.
  • The arithmetic accepts signed values for directed differences. Physical heights and ordinary distances should be entered as nonnegative magnitudes. Display rounding does not improve the precision of a measurement.

Common questions

Can I convert back from the result?

Yes. Enter a known value in another field and leave the original field blank. Every field describes the same underlying length.

How should I read a compound length?

When a compound unit is selected, use colons between the displayed components. A decimal value in feet is not the same as feet followed by inches.
