The following metric scales and their notations are commonly used on mechanical draw-ings: full scale (1:1), half scale (1:2), one-fifth scale (1:5), one twenty-fifth scale (1:25), one thirty-three and one-third scale (1:33 1/3), and one seventy-fifth scale (1:75).
1 cm on the scale drawing represents 12∙5 cm in real life. The drawn length multiplied by 12∙5 gives the real length. The scale drawing enlarges the size of the machine component by scale ...
With scale, you can draw large objects that are too big to be drawn full size at a reduced size or objects that too small to an enlarged size. Architects, engineers and other designers use different types of scales to prepare technical drawing.
1 cm = 1/2.54 inches. Hence, to convert cm to inches, we will divide the centimeters value by 2.54. We can also convert centimeters to inches by multiplying the centimeters value by 0.3937 because one centimeter is approximately equal to 0.3937 inches. For Example:
In this lesson, they extend this work in two ways: They compare areas of scale drawings of the same object with different scales. They examine how much area, on the actual object, is represented by 1 square centimeter on the scale drawing. For example, if the scale is 1 cm to 50 m, then 1 cm\(^2\) represents \(50\cdot50\), or 2,500 m\(^2\).
This post looks at Understanding Scales and Scale Drawings, scale bars, and how to present your drawings at different scales
1 centimeter is a little less than half an inch. 1.6 kilometers is about 1 mile. 1 meter is about 3 inches longer than 1 yard. Mass: 1 kilogram is a little more than 2 pounds. 28 grams is about the same as 1 ounce. Volume: 1 liter is a little more than 1 quart. 4 liters is a little more than 1 gallon.
