About 170 cm in feet
170 cm is 5.577 ft because one foot is 30.48 cm: 170 ÷ 30.48 = 5.577. Going through inches gives the same answer and is easier to read: 170 ÷ 2.54 = 66.93 inches, which is 5 whole feet (60 inches) plus 6.93 inches.
Height is the one place where feet and inches are still used in everyday British and American writing, which is why a figure like 170 cm gets written both ways. 170 cm is close to the 162 cm median adult woman in the same surveys, so it reads naturally as 5′6.9″ on a form that asks for feet and inches.
For a passport, a medical record or a clothing size, quote 170 cm or 5 ft 6.9 in and not both: mixing the two invites a rounding argument. Two decimal places on 5.577 ft already represent about 3 mm, which is finer than any height measurement taken with a wall scale.
Written as a decimal, 170 cm is 1.70 m; in feet it is 5.577 ft, and in inches 66.93. Metric drawings use metres, British property listings use feet, and medical charts use centimetres, so all three turn up for the same 170 cm measurement.
170 cm in feet is the usual way to type this, and the answer is 5.577 ft, or 5 ft 6.9 in to the nearest tenth of an inch. Every one of those forms describes the same length, so pick the one the form in front of you asks for.
