Quantities such as mass, length, and time are examples of scalar quantities. These quantities can be expressed in different units. However, at some point in history, it was decided to standardize these measurements to facilitate international relations. This led to the creation of the International System of Units (SI). Units of Length Units of Area Units of Volume Units of Capacity Units of Mass Units of Time Scale is a tool used to represent real measurements in larger or smaller sizes, maintaining proportionality. The calculation is done through the ratio and proportion between the real dimension and the size presented in the drawing. A scale (E) is simply the relationship between a smaller distance (d) and a larger distance (D). They can be represented by E = d/D, although the most commonly seen representation is: E = d:D See the example: A scale, for example, 1:10,000 indicates that one unit on the map corresponds to 10,000 units on the ground. In other words, considering the centimeter as the unit, 1 cm on the map is equivalent to 10,000 cm on the ground. The larger the denominator, the smaller the scale, the less detail, and the greater the extent of the mapped area. We can classify scales as follows: Reduction scale: The representation of the drawing is smaller than the actual dimensions of the object. Example: 1:100,000. One measurement of the drawing represents one hundred thousand times the actual dimensions. Enlargement scale: The representation of the drawing is larger than the actual dimensions of the object. Example: 10:1. One measurement of the drawing represents one-tenth of the actual dimensions. Questions?
