Unit and Value Marks
Every ruler or number line that uses vertical line segments to mark distance values is using unit & value hatch marks. The marks appear as single vertical line segments that are parallel to each other and evenly spaced. This distance between each mark is one unit. Each mark has a value at that location. The length of the segment is usually an indication of the size of the value. For example, longer line segments are usually used for integers (or just natural numbers). Shorter line segments are usually used for fractions. The hatch mark pattern on the ruler or number line gives the viewer a visual clue as to the value at a certain point on the number line, even if all the hatch marks do not have labels.

“‘Line in nature is not found;

“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
“Now only a dent in the earth marks the site of these dwellings, with buried cellar stones, and strawberries, raspberries, thimble-berries, hazel-bushes, and sumachs growing in the sunny sward there.... These cellar dents, like deserted fox burrows, old holes, are all that is left where once were the stir and bustle of human life, and “fate, free will, foreknowledge absolute,” in some form and dialect or other were by turns discussed.”
—Henry David Thoreau (1817–1862)
