Worth knowing
Height in feet and inches is written with a prime and a double prime — 5′10″ rather than 5.10. That decimal-looking notation causes real confusion, because 5.10 in decimal feet is 5 feet 1.2 inches, roughly nine centimetres shorter than 5 feet 10 inches.
The mistake to avoid
Writing height as a decimal — 5.10 instead of 5′10″ — is the single most common height-conversion error online. Feet and inches are base-12, not base-10, so 5.10 actually means 5 feet 1.2 inches, roughly nine centimetres short of the intended height.

Questions people ask
5 feet 10 inches is exactly 177.80 centimetres, calculated as (5 × 30.48) + (10 × 2.54).
Because feet and inches are not a decimal system. Written properly it is 5′10″. Treating it as the decimal 5.10 feet gives 5 feet 1.2 inches — about nine centimetres shorter.
Use centimetres wherever the form is metric, including most medical and European documents. Keep feet and inches for US paperwork, sports profiles and everyday conversation in English-speaking countries.
Multiply the feet by 30 and the inches by 2.5, then add them, for a rough figure. For anything exact — medical forms, sports registration — use the full factors of 30.48 and 2.54, which give 177.80 cm precisely.
