If you follow these three simple steps, you can be sure to always measure accurately: When you record the measurement, you will always record it using 2 decimal places. Then look at the other end of the object to measure how long it is. Note the hashmark on the ruler along which the other side of the object ends.īefore you start measuring, make sure that one end of the object is lined up with the 0 cm mark on the ruler. Align the object you are measuring along the edge of the ruler. Measuring Objects using a Ruler: To measure the length of an object, place the zero hash mark of the ruler exactly along one end of the object. How do you measure the length of an object with a ruler? Here, the ruler is marked in centimeters (cms) along the top and in inches along the bottom. A ruler or measuring tape can be used to measure lengths in both metric and customary units. The marks or intervals on a ruler are called hash marks.Ī ruler can be defined as a tool or device used to measure length and draw straight lines.
What is a ruler used to measure?Ī ruler, sometimes called a rule or line gauge, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines.Ī ruler or measuring tape can be used to measure lengths in both metric and customary units. The end that comes just before the “1” mark on your measuring tool is the “0” end. If the starting edge of your tool is not marked with a “0,” you can also identify it by locating the number “1” on the tool. Example: Say you’re measuring a piece of cloth and the ruler ends at the fourth line after the 10-inch mark. If you counted in 1/4 inches on a ruler, you’d see that the fourth line after 0 inches equals 1/4 inch, the eighth line equals 2/4 (1/2) inch, and the 12th line equals 3/4 inch. The left side of the line where the object ends will be its measurement in inches. If you are measuring something, align it with the left side of the zero mark on the ruler. Make sure you read the ruler from left to right.
