Height converter

Centimetres, or feet and inches, for standing height.

Calculated in this page. Nothing you type is sent to a server.

Centimetres177.8 cm
Feet and inches5 ft 10 in

An inch is 25.4 mm, so 5 ft 10 in is 177.8 cm. Passports and clinic notes in Ireland use centimetres. The inches left over are shown to one decimal. Shoes off, standing straight, is the height those forms mean.

The factor is exact. The figure on screen is rounded for reading.

How to use it

  1. Type feet and inches, or type centimetres. The field you edit is the one that is converted.
  2. Read the other scale. Inches are shown to one decimal when they do not land on a whole inch.
  3. Measure without shoes if you are filling in a form.

The inch in a person’s height

An inch is exactly 25.4 mm. Five feet 10 inches is 70 inches, which is 177.8 cm. Six feet is 182.88 cm. The page uses that factor both ways: centimetres divided by 2.54 gives inches, then whole feet are taken out at 12 inches each.

A height that lands between inch marks is left as a decimal inch. Rounding 177.8 cm to 5 ft 11 in would add a size that is not there. Forms that want a whole number of centimetres can take 178 for that same 5 ft 10 in.

Where each unit shows up

UK passports and a lot of UK conversation still use feet and inches. Irish passports and clinic notes use centimetres. Clothes labelled in centimetres of inside leg are a length along the leg, which is a different measurement from standing height. Use the centimetres and inches page for a short length such as a hem.

Stand straight, without shoes, with the tape or the book level. Morning height is a little taller than evening height.
