On a ruler or tape measure, 512 millimeters (mm) would be equivalent to 51.2 centimeters (cm) or approximately 20.2 inches. If using a standard ruler, it would extend beyond the typical 30 cm length, requiring a tape measure for accurate measurement. The 512 mm mark would be located a little over halfway between the 50 cm and 60 cm marks on a metric tape.
