![]() ![]() You can also measure the drawing with any metric tape measure and multiply that by the scale ratio. The length of an object represented on a drawing in a metric scale is found by measuring the drawn object with a metric ruler of the proper scale. The ratios most often used in drawings are 1:100 for larger buildings, 1:50 for smaller buildings, and 1:20 for details. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length two common examples are an architects scale and engineers scale. The 1:5 scale (on the bottom) can also be read from left to right (0 to 600 mm) by turning the scale around. The scale labelled 1:50 is read from left to right, from 0 to 15 m. An object 450 mm long would be represented by a line 9 mm long (450 mm/50).įigure 7 shows one of the three sides of a metric scale. This means that the object is 50 times larger than the drawing of it. For example, the scale of 1:50 means that 1 mm on the drawing represents 50 mm on the object. The ratio is marked at the left end of the scale. These are the differences between a ruler and a scale.\)Ī triangular metric scale is similar to the architectural scale in that it has six edges, but it has only one scale ratio per edge. A scale ruler is the three-sided ruler used by architects and readers of blueprints to convert between scaled drawings and the actual dimensions without having to resort to any mathematical calculations. You cannot use a straight edge for it though. ![]() A circular ruler assists you well in measuring the distance around the edge of a curve. ![]() There are circular rulers too and their use is different from the straight edge ruler. A ruler is used very effectively in drawing accurate graphs in algebra and other math topics. Flat white recycled plastic 300mm (6) Oval Scale Ruler comes with 8 different scales, 4 scales a side, in a choice of. Architectural Scale Ruler, 12 Aluminum Architect Scale, Triangular Scale, Scale Ruler for Blueprint, Triangle Ruler, Drafting Ruler, Architect Ruler. Scan above QR code to open browser, and turn your mobile phone screen to landscape mode, so that the length of online ruler will longer. Rapid Rules are ingeniously simple Its unique shape instantly indentifies the scale edge. Turn your smartphone and tablet to a ruler and measure the scale of any small thing. A ruler with straight edge is used with a little bit of an extra advantage than a scale. An Innovative Scale Ruler Ideal for Working With Plans. They also allow you to switch scales as you need. These tools are especially useful for those who need to present their drawing at a particular scale. These tools make it easier to convert any size measurement you want to. The use of scale is simple in purpose whereas that of a ruler is complex in purpose. Another useful tool to find a scale converter is a scale ruler. A ruler need not be used for this purpose. Engineer’s scale is used in measuring the lengths within rooms.Ī scale is virtually used for measurements along a straight line. Linear scale is used in the showing the scale of a map or a chart. Some of them are engineer’s scale, linear encoder, linear scale, vernier scale and architect’s scale. It is interesting to note that there are several kinds of scales. ![]() It is limited in use whereas a ruler is unlimited in use. This is the reason why a ruler often contains calibrated lines that are employed in measuring distances.Ī scale on the other hand is simple kind of ruler that is used in geometry to measure length. Since it rules lines it is called as a ruler. It is important to know that a ruler is necessarily a straightedge to draw or rule lines. It is an instrument used often in geometry and engineering drawing. There is some difference between their connotations.Ī ruler is sometimes called as a rule or simply as line gauge. The scale labelled 1:50 is read from left to right, from 0 to 15 m. Scale and Ruler are two words that are often confused as words that denote one and the same object. ![]()
