Why this conversion is exact
The international inch has been defined as exactly 25.4 millimetres since the 1959 International Yard and Pound Agreement, so centimetre-to-inch conversion is an exact definition, not a measurement. One foot is exactly 12 inches. Only the displayed rounding — inches to one decimal place, centimetres to one decimal place — introduces any approximation.
