How to convert 178 cm to feet

There are 30.48 centimetres in one foot, so divide the height in centimetres by 30.48: 178 ÷ 30.48 = 5.840 feet. To get feet and inches instead, take the whole number of feet (5) and multiply the leftover 0.840 of a foot by 12, which gives 10.1 inches.

Quick mental method: divide by 30 for a rough answer (178 ÷ 30 ≈ 5.9 ft), or work in inches by dividing by 2.5 (178 ÷ 2.5 ≈ 71 in). The exact figure uses 2.54 cm per inch.

That depends on age, sex and which group you compare with, so there is no single answer. Below, 178 cm is placed against two official US reference sources: the CDC growth charts for children and teenagers, and the national health survey (NHANES) for adults. A percentile is a ranking against a reference group, not a verdict on health: the 50th percentile means half the reference group are shorter.

Where 178 cm falls at each age (percentile of the CDC stature-for-age chart, calculated with the LMS values CDC publishes):

Ages are birthdays (the CDC table row for the start of that year). The CDC charts describe US children. The NHS and UK health professionals use the UK-WHO growth charts from the Royal College of Paediatrics and Child Health, which can give slightly different results. If you are worried about a child’s growth, ask a GP or health visitor.
