5 Feet 6 Inches in cm
5' 6" is

66 inches, and 167.64000000000001 cm exactly — not approximately. The inch has been defined as 25.4 millimetres since 1959, so this conversion is a definition rather than a measurement, and it has no error term.

This one lands on a whole inch with nothing to round, which is why the two sides agree exactly.

Why the answer is rounded at all
An inch is exactly 25.4 millimetres, fixed by agreement in 1959 rather than measured, so every conversion here is exact until somebody asks for it in feet and inches. A round centimetre almost never lands on a whole inch: 170 cm is 66.93 inches, which is 5 feet 6.93 inches. Every official record — licence, passport, medical chart — rounds that to the nearest whole inch, and so does the figure at the top of this page. The exact number is in the table above, where it belongs.
