📏 Length & height
5′5″ in cm
5′5″ is 165.1 cm. Feet and inches are converted by taking the total inches first (5 × 12 + 5 = 65 in) and multiplying by 2.54.
The short answer
5′5″ = 165.1 cm
5 feet 5 inches, or 65 inches in total.
About 5′5″ in cm
5′5″ is 165.1 cm because one inch is exactly 2.54 cm. The working is 5 × 12 = 60 inches for the feet, plus 5 inches, giving 65 inches; 65 × 2.54 = 165.1 cm. Nothing is rounded along the way, so the answer is exact.
This notation is still how height is quoted in Britain, Ireland and the United States, while most of the rest of the world uses centimetres. 5′5″ sits below the 175 cm median adult man, which is the comparison most people are really making when they convert it.
On a form, write 165.1 cm rather than 5′5″, and keep the same precision throughout: if a chart plots 165.1, do not enter it as 5′5″ or as 165 cm, because the two roundings can disagree by a whole centimetre across a series of measurements.
Converting 5′5″ the other way is the same multiplication in reverse: 165.1 cm ÷ 2.54 = 65 inches, and 65 inches is 5′5″. Because 2.54 is exact, no rounding creeps in whichever direction you go; only the displayed precision changes.
Typed without the prime symbols, 5'5 in cm is the same question and has the same answer: 165.1 cm. Rounded to a whole centimetre that is 165 cm, and a tape measure marked in centimetres will read 165 rather than the exact decimal.
How the calculation works
- Total inches = 5 × 12 + 5 = 65 in
- 65 in × 2.54 = 165.1 cm
- 5′5″ in metres = 1.6510 m
