Hatch marks, sometimes also called hash marks, or tick marks, are a form of mathematical notation. They are typically used three ways:

  • Unit and value marks – as on a ruler or number line.
  • Congruency notation – as on a geometric figure.
  • Graphed points – as on a graph.

Hatch marks are frequently used as an alternate form of abbreviation for some common units of measurement.

In regard to distance, a single hatch mark typically indicates feet and a double hash mark indicates inches within the English system. In regard to time, a single hatch mark indicates minutes and a double hatch mark indicates seconds; these typically occur following hours, indicated by an elevated circle. The same system is used within Geometry and Trigonometry for the measurement of angles in degrees, minutes and seconds.
