What do the numbers on a scale ruler mean?
An Architect’s or scale ruler is designed for use in determining the actual dimensions of a distance on a scaled drawing. 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.
How do you read scale drawings?
The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing. Example: this drawing has a scale of “1:10”, so anything drawn with the size of “1” would have a size of “10” in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.
How many scales are on an architect’s ruler?
For accuracy and longevity, the material used should be dimensionally stable and durable. Scales were traditionally made of wood, but today they are usually made of rigid plastic or aluminum. Architect’s scales may be flat, with 4 scales, or have asymmetric 3-lobed cross-section, with 6 or 12 scales.
How do you read scales on architectural drawings?
For example, a floor plan of a building drawn using a metric scale of 1:100 (pronounced “one to a one hundred”), means that for each unit that is measured on the drawing (the 1), the real world size of it is 100 times larger (the 100) than it appears.
What does a 1/4 scale mean?
Example – Blueprint Drawing Scale 1:50 An actual length of 1 cm is measured on a 1:50 blueprint floor plan. The physical length can be calculated as. (1 cm) 50 = 50 cm. Imperial Units – US. A 1/4″ scale means that each 1/4″ (inch) on the plan counts for 1′ (feet) of actual physical length.
What does a 1/2 scale mean?
Half scale is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. This means the drawing of the object is twice as large as the object itself. Designers use an enlarged scale, such as double scale, on objects that are too small to draw full size with any meaningful detail.
How do you read cm on a ruler?
Each centimeter is labeled on the ruler (1-30). Example: You take out a ruler to measure the width of your fingernail. The ruler stops at 1 cm, meaning that your nail is precisely 1 cm wide. So if you counted five lines from 9 cm, for instance, you’d get 9.5 cm (or 95 mm).
What are architectural measurements?
Drawing Size Reference Table, Architectural and Engineering Drawing Sizes Standard US Architectural Drawing Sizes Drawing Size Dimensions (millimeters) Dimensions (inches) ARCH A 228.6 x 304.8 9 x 12 ARCH B 304.8 x 457.2 12 x 18 ARCH C 457.2 x 609.6 18 x 24.
How do you read a 1 75 scale?
On this scale, each small division represents 2 mm, and each longer bar represents 10 mm. On the 1:75 scale, the intermediate is not numbered, but it is there at, again, 500 mm. The 1, 2, 3, etc are metres, and each small division is 5 mm. You just have to use the scales to get a feel for the divisions.
How do you read a blueprint scale?
Lay the proper scale next to the item on the drawing and take the measurement. The scale will translate for you. As an example, a 1/4 inch = 1 foot architect scale will have markings that increase by 1 foot every 1/4 inch; a 4 foot wall is represented by a 1-inch length, if measured with a conventional ruler.
What are all of the scales on the architects scale?
Common scales for a triangular architect’s scale are: 16 (full), 3, 1-1/2, 1, 3/4, 1/2, 3/8, 1/4, 1/16, 1/8, 3/32. Major divisions of each scale represent feet which are further subdivided into 12ths or 16ths. A scale labeled 1/8 translates to 1/8″ = 1′ or 1/96 scale.
How do you calculate scale?
To scale an object to a larger size, you simply multiply each dimension by the required scale factor. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 5 cm, you simply multiply 5 × 6 = 30 cm to get the new dimension.
What does scale 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.
What does a 1/8 scale mean?
Scale is a measurement we use to give customers an idea of how big your model will be when comparing to the real-life object. If you see the scale 1:8, this means your completed model will be eight times smaller than the real thing.
What is a 1/6 scale?
Items in 1:6 scale, also known as “Playscale” or “Fashion Doll” scale, are sized to fit with common fashion dolls such as Barbie or collectible action figures, principally military action figures. In this scale, 1 inch is equivalent to 6 inches in full size.
What is the standard architectural scale?
Architect scales, such as 1/4˝ = 1´-0˝ (1/48 size) or 1/8˝ = 1´-0˝ (1/96 size), are used for structures and buildings. They are used to measure interior and exterior dimensions such as rooms, walls, doors, windows, and fire protection system details.
How do you use a 1/10 scale?
In the real world, one meter is equal to one meter. A drawing at a scale of 1:10 means that the object is 10 times smaller than in real life scale 1:1. You could also say, 1 unit in the drawing is equal to 10 units in real life.
What does a 1/100 scale mean?
Ratio scales If the scale of the plan is 1 : 100, this means the real measurements are 100 times longer than they are on the plan. So 1 cm on the plan represents a real length of 100 cm (1 metre).
Which side is cm on a ruler?
The metric side of the ruler has centimeter numbers from 1 on the far left up to 30 on the far right. The final metric point on the ruler is 30.5, making the ruler 30.5 cm long. The longest lines at each centimeter number indicate the centimeters along the edge of the ruler.
Is a ruler cm or MM?
A metric ruler is the standard instrument for measurement in the scientific laboratory. On a metric ruler, each individual line represents a millimeter (mm). The numbers on the ruler represent centimeters (cm). There are 10 millimeters for each centimeter.
