How to convert it
- Divide by 2.54 to get inches: 175 ÷ 2.54 = 68.8976 in.
- Divide by 12 for feet: 68.8976 ÷ 12 = 5 ft with 8.8976 in left over.
- Result: 5 ft 8.9 in, which rounds to 5′9″.
total inches = cm / 2.54; feet = floor(inches / 12); remainder inches = inches mod 12
As a height, 175 cm is about the same as the average US adult man (≈175.3 cm) and 13.7 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.
