170 cm converts to about 66.93 inches, which is 5 feet 6.9 inches, usually rounded to 5′7″; in decimal feet it is about 5.58 ft. Height brackets on clothing size charts, bike frame guides and desk height recommendations are often written in feet and inches, and 170 cm sits right around the boundary of many of them.
Formula: ft = cm ÷ 30.48, in = cm ÷ 2.54. Example: 170 cm = 5.58 ft. Table values are rounded to two decimal places (one for temperatures); use the converter above for more precision.
The math: 170 ÷ 2.54 = 66.93 inches, and 66.93 ÷ 12 = 5 remainder 6.93, so 5 ft 6.9 in. Many forms only accept whole inches, in which case 5′7″ is the right choice; 5′6″ would be about 167.6 cm.
