So, the pointer is on 5 inch.Siem Reap ( Khmer: សៀមរាប, Siĕm Réab ) is the second-largest city of Cambodia, as well as the capital and largest city of Siem Reap Province in northwestern Cambodia. The pointer is on the hash that shows 5 written on it. The pointer is on the side of the ruler that shows the measurement in inches. So, the pointer is on 17.5 cmĮxample 4: Write the reading shown by the pointer. The pointer is on the 5th hash mark from 17. The pointer is on the hash mark which is between 17 and 18. So the length of the comb is 4 inches.Įxample 3: Write the reading shown by the pointer. Zero hash mark is at one end and another end is at hash mark with 4 written on it. So, the length of the pencil is 11 cm.Įxample 2: Measure the length of comb in inches. The tip of the pencil is on zero (‘0’) and the end of the pencil is on hash showing 11.

For taking measurements before and during construction.Įxample 1: Measure the length of the pencil in cm.

For engineering purposes where accurate measurements are required.

To measure the length and width of different objects.

Take a ruler and mark a point at one end the other point at the given length.

Place the ruler in a specific place where you want to draw a straight line.Mathematically we can calculate it as 12 – 3 = 9 cm.

The given object is not 12 cm long as it didn’t start at the edge of the ruler (zero). When the object is placed in the middle of the ruler and it doesn’t start at zero we need to observe the starting position where the object is placed.

How to read when the object is not placed at 0? The big long hash marks above which numbers are written on the opposite side of the centimeter ruler denote inches. The smaller hash marks between each centimeter represent millimeters.ġ0-millimeter hash marks make 1 centimeter.Īn inch is bigger than a centimeter. The long hash marks under which numbers are written on the ruler denote centimeters.Ī millimeter is even smaller than a centimeter. Here, the shoelace is 17.6 cm long in metric units of length, and 7 inches long in customary units of length.Ī centimeter is smaller than an inch. Note the hashmark on the ruler along which the other side of the object ends. Align the object you are measuring along the edge of the ruler. To measure the length of an object, place the zero hash mark of the ruler exactly along one end of the object. Short rulers are 15 centimeters which are very convenient to carry and long rulers are 30 centimeters or 12 inches long, it is useful to draw larger drawings.ĭepending on its usability, specially in the industries, rulers are also used in different formats like: Folding Ruler or Extension Ruler, Self-retracting Metal Tape, Plastic tape or a Soft Ruler. Rulers are made in many different materials like wood, plastics, and metal.ĭepending on the size of the ruler there are two types of ruler – a short ruler and a long ruler. There are different types of ruler depending on the material it is made of. The rulers are marked with standard distance in centimeters in the top and inches in the bottom and the intervals in the ruler are called hash marks. A ruler can be defined as a tool or device used to measure length and draw straight lines.Ī ruler is used to measure the length in both metric and customary units.
