RULER MARKINGS FULL
The big and red lines represent a full inch and the distance between them is one inch.Let’s say that if the measurement is past the 1″ mark, simply use the number on the ruler and add the fraction, for example, if you’re two ticks past the 5” mark then the measurement is 5*1⁄8”.
RULER MARKINGS HOW TO
How to read a ruler in inches? First of all, the lines on a standard inch ruler represent the fractions of an inch. Measurements on an Inch Ruler – Imperial System Therefore to convert millimeters until meters divide the number by 10 to get the correct value. One decimeter (1 dm) is one-tenth of a meter (1/10 m). One centimeter (1 cm) is one one-hundredth of a meter (1/100 m). So one millimeter (1 mm) is one one-thousandth of a meter (1/1000 m). Measure of Lengths – Conversion Table Millimeters (mm) to Centimeters (cm) to Decimeters (dm) to Meters (m) Conversion Chart mm Each line (1 mm) on a metric ruler represents.
Ten lines or millimeters make up a centimeter. The bigger lines with the numbers make up the centimeters. On a metric ruler, each small mark (line) represents a mm. Most measurements in science class are done using a smaller scale then a meter which is either centimeter (cm) or millimeter (mm). In the metric system, the meter is the the standard unit for measurement. Reading Ruler Measurements – Metric System The 100 mm (10 cm), 200 mm (20 cm), 300 mm (30 cm), mm – millimeters, cm – centimeters rulers are using the metric system. Rulers can vary in length and systems, like the 6” and 12” (in or inches) ones, they are using imperial system. These type of rulers have different names such as plastic or wooden rulers, architects scales, carpenters rules, seamstress tapes, measuring tapes and yardsticks. Like most rulers, they are mostly used in school for math, geometry and technical drawing, as well as the engineering and construction, carpentry, sewing, printing and many more other industries. These type of rulers for precision measurements may be have to be certified by NIST (National Institute Of Standards and Technology), to be more accurate, by the Dimensional Metrology Group of the US government. When it comes to accuracy the best material for a ruler has to be steel which is durable and rigid. In our case, the rulers you will find here are made to be printed on sheets of paper. Depending on the rigidity, lightweight or how often will be used, rulers can be made out of different materials such as metal, wood or plastic. So till then Keep Practicing.A ruler, also known as “rule” or “line gauge”, is a thin rectangular measuring device that has straight edges and length measurement markings, equidistant & parallel lines with numbers, along the edge. I will come back with more different topics.The only way to get an edge of it is keep practicing of what you have learnt. So guys hope you have enjoyed learning How to read a ruler. For illustration if you have 3/2 as a reading then write it like 1+1/2.Īlso you can go through this YouTube video to learn more about reading English ruler:
Also while converting it into calculation you need to separate out the fraction part from the whole part. Then combine both of these to get the exact reading. While reading the ruler first mark down the whole inch and then mark down the fractions. The first smallest mark with two big lines is ½. In first one every mark is 1/8 th of an inch and in the second one every mark is 1/16 th of an inch. One is with 8 markings and other one is with 16 markings. All the calculations involve in it deals with the fractions and fractions are something which we are not much comfortable with. Now coming to English ruler is a bit difficult to read. You can also go through this YouTube video for its tutorial. Since 1 millimeter is 1/10 th of a centimeter so if you will measure five big lines and after that two small lines then it is equivalent to 5.2. Here big lines denote the centimeter lines and the small lines denote millimeter lines. Now let us take a look at this metric ruler. This conversion relationship is as follows:
The only concept used in reading this type of scale is the conversion of centimeter to millimeter. It only deals with the easy concepts of centimeters and millimeters. It is quite easy to deal with metric rulers.
