The inch has been defined as exactly 2.54 cm since the 1959 international yard and pound agreement, so this conversion carries no rounding error at source. Watch the two-step trap with heights: converting 180 cm gives 70.87 inches, which is 5 ft 10.87 in — rounding to "5 ft 11" is fine for most purposes but loses about 3 mm.
