What are ruler measurements?
A ruler or measuring tape can be used to measure lengths in both metric and customary units. Here, the ruler is marked in centimeters (cms) along the top and in inches along the bottom. The marks or intervals on a ruler are called hash marks.
What is a drafting scale?
Scale – In drafting, architecture and engineering the term scale has two meanings. A scale is a dimension that represents the structure shown in a plan. A scale is also a ruler used in drawing and measuring architectural and engineering plans. Architectural scales units are based on foot/inch dimensions.
What is the use of ruler in drafting?
A ruler is a stationery item and drafting tool used when drawing lines, as a guide for cutting, and for various other uses. It is available in different shapes and materials, depending on the type of lines the user wishes to draw. Some rulers have measurement gradations and can be used for measuring length.

Metric units In Britain, and elsewhere, the standard units used on architectural drawings are the (SI) units millimetres (mm) and metres (m), whereas in France centimetres (cm) and metres are most often used. In Britain, for flat rulers, the paired scales often found on architect’s scales are: 1:1/1:10.
What are the different types of scales in engineering drawing?

- Plain scale.
- Diagonal scale.
- Vernier scale.
- Comparative scale.
- Scale off chords.
What is a drafting paper?
