Worked example
178 ÷ 2.54 = 70.08 inches. 70.08 ÷ 12 = 5 feet with 10.1 inches left over, so 5′ 10.1″ (1.78 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 178 cm is taller than the average man and taller than the average woman.
