How To Read A Ruler?

Given some object, to read a ruler line up one of the sides of the ruler with the beginning of the object. On an inch ruler every number indicates a whole inch; each line between indicates a fraction (1/2, 1/4, 1/8, 1/16). There are centimeter markings on a metric ruler and one small line represents one millimeter (10 mm = 1 cm).
 
To read a standard ruler:
  1. Identify units (inches/cm) – inches are divided into 16ths (or 8ths/metric into 10mm/cm).
  2. Whole numbers mark full inches (or cm).
  3. Smaller lines between show fractions:
    • ½" (midpoint), ¼", ⅛", etc.
  4. Metric rulers use millimeters (10mm = 1cm).
 
To read a ruler, first identify whether it's using inches or centimeters. Align the ruler's zero mark with one end of the object you're measuring. Then, observe the markings on the ruler to determine the distance to the other end of the object.
 
To read a ruler:
  • Look at the numbered marks for inches (1, 2, 3...)
  • The small lines between the numbers show fractions of an inch, like ½, ¼, ⅛, etc.
  • On a metric ruler, the long lines show centimeters (cm), and the smaller ones show millimeters (mm).
Count the marks based on your unit (inches or centimeters) to measure length accurately.
