5 foot 11 in cm
5′11″ = 180.3 cm = 1.803 m = 71 inches
Working: (5 × 12 + 11) × 2.54 = 180.34
5 feet 11 inches is 180.3 centimetres, or 1.803 metres.
Convert in two steps. Turn the height into inches first — 5 × 12 = 60, plus 11 gives 71 inches. Then multiply by 2.54, since one inch is defined as exactly 2.54 cm: 71 × 2.54 = 180.34 cm.
Unlike the reverse conversion, this direction is exact: feet and inches are whole numbers and the factor is exact, so 5′11″ is precisely 180.34 cm with no rounding involved. Rounded for a form that wants whole centimetres, it is 180 cm.
This is the conversion most often got wrong in the other direction. Five foot eleven is 180.34 cm, so someone who describes themselves as 180 cm is 5′11″, not six foot — six feet being 182.88 cm. The two round numbers sit an inch apart and get conflated constantly on any form recording both.
