An Architect’s or scale ruler is designed for use in determining the actual dimensions of a distance on a scaled drawing. Most architectural, construction and engineering drawings and blueprints are scaled to allow for large areas, structures or items to conveniently fit on a reasonable size of paper.

Measuring with a **Scale Ruler** Common **scales** are 1/2, 1/4 and 1/16. To read a blueprint with a **scale ruler** once the appropriate **scale** is determined, line up the zero mark with the beginning of the length to be measured. If the distance falls exactly on a line of the **ruler**, that is the measure in feet.

how do you use a metric scale ruler? The “meter” is the base unit for length measurement in the **metric** system. One tenth of a meter is a decimeter, one hundredth of a meter is a centimeter and one thousandth of a meter is a millimeter. Locate the side of the **ruler** that has centimeters and millimeters.

Correspondingly, how do you use a triangular scale ruler?

**How to Use a Triangle Scale Ruler**

- Unroll the blueprint on the surface of the worktable.
- Determine the scale of the blue print.
- Flip the architects rule around until you find the side of the rule that reads 1/4.
- Place the zero point of the triangle scale on one point of the blue print.

How do you convert scales?

For example, if the **scale** factor is 1:8 and the real measurement is 32, divide 32 ÷ 8 = 32 to **convert**. To **convert** a measurement to a larger measurement simply multiply the real measurement by the **scale** factor. For example, if the **scale** factor is 1:8 and the measured length is 4, multiply 4 × 8 = 32 to **convert**.

### How do you calculate a scale?

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

### How do you use a scale?

Using a Bath Scale: Calibrate your scale. This ensures the reading you receive is an accurate one. Place the scale on a hard surface. When preparing to weigh yourself, place your scale on a hard surface, such as a tile floor. Use on a level surface. Keep it personal. Use it in the morning. Wait for digital scales.

### How do you draw a scale?

Steps Measure the object you’ll be scaling. Choose a ratio for your scaled drawing. Convert the actual measurements with the ratio. Start drawing the perimeter with a straight segment when possible. Refer to the original drawing frequently. Use a piece of string to check the scaled lengths of irregular images.

### How do you use a 1/8 scale?

For example, 1/8 on the ruler is in fact a scale that converts 1/8 inch on the drawing to 1 foot. This would represent a drawing with a scale of 1/8″ = 1 foot. Be careful when selecting the scale on the ruler, there are two scales on each edge. One scale reads left to right and the other right to left.

### What is a 3 sided ruler called?

The drafter’s ruler (also called an architect’s scale) has three sides with one or two scales along each of its six edges. The other scales are used to make reduced drawings. Using a three-sided drafter’s ruler isn’t too difficult if you know what to do with it.

### How do you use a ruler?

Method 4 Measuring an Object Using a Ruler Measure with a ruler or tape measure. Place the zero end of your rule at the end of your object. Move to the opposite side of the object you are measuring. Use a metric or decimal rule with a metric ruler. Use a tape measure to measure between objects, for instance, walls.

### What is the definition of 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 is a 1 40 scale?

It is used in making engineering drawings, commonly called blueprints, blue lines or plans in a specific scale. Typically in civil engineering applications, 1:10 (1″=10′) is used exclusively for detail drawings. 1:20 and 1:40 scales are used for working plans.

### What are the major parts of the triangular scale?

Triangular Scale Signed W. The first two inches are divided to 1/128″; the next two inches are divided to 1/64″; inches 4–6 are divided to 1/32″; inches 6–8 are divided to 1/16″; and inches 8–12 are divided to 1/8″. The third face also has a scale of inches numbered by ones from 1 to 12.

### What does a scale of 1 50 mean?

1:50 is a ratio. it means you’re scaling 1 unit to 50 units. that could be inches (1″=50″) or miles (1 mile=50 miles) or anything else, but it’s a direct scale. that works better in metric, because their units scale in multiples of 10.
