What this conversion means in practice
EU listings and body measurements often arrive in centimeters; US forms still want inches. The inch is defined as exactly 2.54 cm, so this conversion is exact, not approximate.
One hundred seventy-five centimeters is about 68.9 inches (roughly 5 ft 9 in). Do not multiply by 0.39 twice after a spreadsheet already converted the column.
One centimeter is about 0.3937 inches. The table scales the same factor for room dimensions and display diagonals.
