These tiny lines that represent 1/16 inch come between all 1/8-inch lines: Example: You’re trying to measure the length of your pointer finger. Finally, the smallest unit on a ruler is 1/16 inch. This would mean that the corn is 6 1/8 inches long. You find that your ruler comes to the second line after the 6-inch mark. Then follow these three steps to measure the length of the object: Be sure to avoid a parallax error, or the apparent motion of an object when viewing it along different lines of sight. When using a metric ruler, line one end of the object up with the 0 cm mark.
#METRIC RULER HOW TO#
How to measure the length of an object with metric ruler? In total, there are three different lengths of lines on a metric ruler. There will always be 10 lines from one centimeter to the next centimeter. How many lines are on a millimeter ruler?Įach line represents 1 millimeter, which is equal to 1/10 or 0.1 cm (so 10 mm make up 1 cm).
There are smaller lines between the larger centimeter lines, which represent millimeters. The distance between them is equal to 1 centimeter. To read a metric ruler to measure centimeters, look at the long lines on the ruler that are numbered 1-30, which are the centimeter marks. If you counted each line within the first inch of a ruler, you’d get the following measurements: 1/16 inch. (Note that some rulers only go down to 1/8 inch lines, whereas others go down to 1/32 inch lines.) What is the smallest unit in a ruler?įinally, the smallest unit on a ruler is 1/16 inch. What are the smallest lines on a ruler?Įach inch is divided into 16 lines, meaning that the space between each line is 1/16 inch long-this is the smallest length you can measure with a ruler. The left side of the line where the object ends will be its measurement in centimeters. If you are measuring an object, align it with the left side of the zero mark on the ruler. Make sure you read the ruler from left to right. What are the lines between cm?īetween each centimeter (cm) mark, there should be 10 smaller marks called millimeters (mm). The units of length most commonly used include the meter (m), centimeter (cm), millimeter (mm), and kilometer (km).Įach line represents 1 millimeter, which is equal to 1/10 or 0.1 cm (so 10 mm make up 1 cm). A metric ruler or meter stick are the instruments (tools) used in measuring length. The basic unit of length in the metric system is the meter. The centimeter is the next smallest unit of measurement.
A millimeter would be used to measure something that is very small, like a seed. The abbreviation for millimeters is mm (for example, 3 mm). The millimeter is the smallest commonly used unit in the metric system. What are the small units called on a metric ruler? Hatch marks mark distance values on the ruler and notify you every unit of distance moved along a straight line. Hatch marks are also known as hash marks. “Hatch mark” is the name given to a mark on a ruler. What are the lines on a metric ruler called? Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long. The larger lines with numbers are centimeters, and the smallest lines are millimeters. Take a look at the following Metric Ruler.
