180 cm converts to about 70.87 inches, which is 5 feet 10.9 inches, usually rounded to 5′11″; in decimal feet it is about 5.91 ft. “Six feet” is 72 inches, or 182.88 cm, so 180 cm is about 2.9 cm short of six feet.
Formula: ft = cm ÷ 30.48, in = cm ÷ 2.54. Example: 180 cm = 5.91 ft. Table values are rounded to two decimal places (one for temperatures); use the converter above for more precision.
The math: 180 ÷ 2.54 = 70.87 inches, and 70.87 ÷ 12 = 5 remainder 10.87, so 5 ft 10.9 in. To go the other way, use (feet × 12 + inches) × 2.54; for example, 6′0″ = 72 × 2.54 = 182.88 cm.
