Measuring Length in Inches
An inch is a small unit of measurement used in the United States to describe how long, wide, or tall something is. An inch is about the length of a quarter or a paperclip. It can be used to find the size of things like cell phones, laptops, trading cards, and food. Inch can be abbreviated with the letters I N period or with one set of quotation marks that follow the number.
To find an object's size in inches, we can use a measuring ruler in inches to determine its length. Rulers are tools that give us precise, or exact, measurements in a given unit.
Measuring Lengths in Inches with Rulers
To practice measuring in inches with a ruler, let's use the order in the image below. First, line up one end of the food with the zero mark of the ruler.
Next, find the other end of the food and determine which mark it is closest to.
Then, read the number at the inch mark to find the length of the object. Here it lines up with the number eight.
Lastly, record the measurement by writing the number and labeling it in inches.
