168 cm = 5 ft 6.1 in
Worked example
168 ÷ 2.54 = 66.14 inches. 66.14 ÷ 12 = 5 feet with 6.1 inches left over, so 5′ 6.1″ (1.68 m).
For comparison, the CDC reports average US adult height as about 69.0 in for men and 63.5 in for women (NHANES 2015–2018), so 168 cm is shorter than the average man and taller than the average woman.
