# How do you write a scale in engineering drawing?

**SCALES**

- Representing
**scales**: The proportion between the**drawing**and the object can be represented by two ways as follows: - a)
**Scale**: - 1cm = 1m or 1cm=100cm or 1:100. - There are three types of
**scales**depending upon the proportion it indicates as. **Scale**: - 1cm=100cm or 1:100 and by RF=1/100 (less than one)

Also asked, what is a scale in engineering drawing?

The proportion by which the **drawing** of an object is enlarged or reduced is called the **scale** of the **drawing**. A **scale** is defined as the ratio of the linear dimensions of the object as represented in a **drawing** to the actual dimensions of the same.

Furthermore, what is comparative scale in engineering drawing? **Scales** on **drawings** are the size of the view on the paper relative to real size. Sometimes one or two rulers are displayed at a **scale** to show distances on the **drawing**. **Comparative scales** might show two rulers or objects using different units or different **scales** in the same units.

Moreover, how do you draw a scale?

To **scale** a **drawing** by hand, start by measuring the width and height of the object you'll be scaling. Next, choose a ratio to resize your **drawing**, such as 2 to 1 to double the image in size. Then, multiply your measurements by the first number in your ratio to increase the size.

What is the scale of 1 100?

The **1**:**100** ratio is that of a centimeter to a meter. That is, **1** cm of a model is equal to **100** cm when the product is actually built, or if its the representation of a map, a centimetre on the map is equal to a metre when realistic distance between the two places in the map is to be considered.
