To convert 18mm to inches, you can use the conversion factor of 1 inch equals 25.4mm. Therefore, 18mm is approximately 0.71 inches (18 mm ÷ 25.4 mm/inch). On a ruler, you would find 0.71 inches slightly less than three-quarters of an inch. It may not be marked directly on a standard ruler, but you can estimate it between the 3/4 inch and 1 inch markings.
