How to convert it
- Convert to inches: 5 × 12 + 6 = 66 in.
- Multiply by 2.54: 66 × 2.54 = 167.64 cm.
- Result: 5′6″ = 167.64 cm, or 1.6764 m.
cm = (feet x 12 + inches) x 2.54
As a height, 167.6 cm is 7.7 cm shorter than the average US adult man (≈175.3 cm) and 6.3 cm taller than the average US adult woman (≈161.3 cm), based on CDC NHANES 2015–2018 averages.
Height forms in the US and UK usually want whole feet plus inches, rounded to the nearest inch — use the rounded value above for those.
