How to convert it
- Divide by 2.54 to get inches: 142 ÷ 2.54 = 55.9055 in.
- Divide by 12 for feet: 55.9055 ÷ 12 = 4 ft with 7.9055 in left over.
- Result: 4 ft 7.91 in, which rounds to 4′8″.
total inches = cm / 2.54; feet = floor(inches / 12); remainder inches = inches mod 12
As a height, 142 cm is 33.3 cm shorter than the average US adult man (≈175.3 cm) and 19.3 cm shorter 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.
