On a ruler, 20mm is equivalent to 2 centimeters, which is typically marked as a small line or number between the 1cm and 3cm marks. If the ruler has millimeter markings, you will see a line at the 20mm mark that is slightly longer than the others, usually indicating a full centimeter. It’s a short distance, roughly the width of a large paperclip.
