## What is the triangular scale?

A triangular scale is a ruler that has a 3-lobed cross-section with 6 different types of scales on the edges (2 on each face) used for measuring and preparing scale drawings such as blueprints and maps. It is also called an architect’s scale.

**What are the scales on an engineer ruler?**

Engineer scales have numbers that run incrementally from left to right. The whole number to the left of the number line indicates the scale those numbers represent. The scale marked “16” is a standard ruler. You must learn to read both from left to right, and right to left.

### How do you use a triangular scale 1 100?

A scale of 1 to 100 is indicated on a drawing using the code 1:100. This can be interpreted as follows: 1 centimetre (0.01 metre) measured with a ruler on the plan would need to be multiplied by 100 to give the actual size of 1 metre.

**What is the difference between architect and engineer scale?**

Although similar in appearance to an architect’s scale, the engineering scale is designed to be more precise and has a decimal scaling scheme whereas an architect’s scale uses fractional scaling. It is designed to only be read from left to right. An architect’s scale can be read from either the left or right side.

**How do you calculate the scale?**

The basic formula that is used for calculating the scale factor is, Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.

## What is the formula for scale drawing?

Calculating the Actual Distance using the Scale If the scale is 1 : x, then multiply the map distance by x to calculate the actual distance.
