What is imperial scale and metric scale?
Most countries use the metric system which uses the measuring units such as meters and grams, and adds prefixes like kilo, milli, and centi to count orders of magnitude. In the United States, we use the older imperial system, where things are measured in feet, inches, and pounds.
What is metric scale drawing?
Metric Scale
It is helpful to think of this as one unit on the drawing equals two units on the object. A small object can be enlarged on the paper and drawn in 2:1 scale. This means the drawing of the object is twice as large as the object itself.
How do you convert imperial scale to metric?

What are imperial scales?
Typically, a scale factor is unit-less; a scale factor of 48 (or 1:48) is saying that for one unit on the page, it represents 48 of the same units in real life. This is a bit different than a scale; an imperial scale is described as a ratio of inches-to-the-foot.
Which is best metric or imperial?
Metric is simply a better system of units than imperial
The metric system is a consistent and coherent system of units. In other words, it fits together very well and calculations are easy because it is decimal. This is a big advantage for use in the home, education, industry and science.
What are the 3 measurement systems?
The three standard systems of measurements are the International System of Units (SI) units, the British Imperial System, and the US Customary System. Of these, the International System of Units(SI) units are prominently used.
What are the 4 main types of scales used for drafting?
Scales used in drafting include the mechanical engineer’s scale, the civil engineer’s scale, the architect’s scale, and the metric scale.
What are the standard drawing scales?
Scales are generally expressed as ratios and the most common scales used in furniture drawing are 1:1, 1:2, 1:5, and 1:10 for reducing and possibly 2:1 for enlarging.
How do you convert scales to drawings?
To convert a scaled measurement up to the actual measurement, simply multiply the smaller measurement by the scale factor. For example, if the scale factor is 1:8 and the smaller length is 4, multiply 4 × 8 = 32 to convert it to the larger actual size.
In what units is the scale drawings?
A scale tells how the measurements in a scale drawing represent the actual measurements of the object. For example, the scale on this floor plan tells us that 1 inch on the drawing represents 8 feet in the actual room. This means that 2 inches would represent 16 feet, and 12 inch would represent 4 feet.
Why do people still use imperial?
The reason for the continued use of Imperial Units in the U.S. is because of tradition and the purpose they serve. The real reason any society would prefer one form of measurement over another is the purpose it serves.
Why is America not on metric?
The biggest reasons the U.S. hasn’t adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.
What are the 7 basic units of measurement?
The seven SI base units, which are comprised of:
- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)
What are the 2 main systems of measurement?
The two systems used for specifying units of measure are the English and metric systems.
What scales are used in drawings?
How do you read scale drawings?
Basically the scale is represented by two numbers in a ratio, with the first number being how many centimeters are shown on your drawing followed by the second number which is separated by a colon (“:”), then the matching length of the real item to be built.
What are the types of scale drawing?
The scales in engineering drawing are classified as the following:
- Plain scale.
- Diagonal scale.
- Vernier scale.
- Comparative scale.
- Scale off chords.
Why does the US not use metric?

A 45-member advisory panel consulted and took testimony from hundreds of consumers, business organizations, labor groups, manufacturers, and state and local officials. The final report of the study concluded that the U.S. would eventually join the rest of the world in the use of the metric system of measurement.

Length: Millimeter (mm), Decimeter (dm), Centimeter (cm), Meter (m), and Kilometer (km) are used to measure how long or wide or tall an object is.
What are the 10 unit of measurement?
Linear Measure
10 millimeters (mm) = | 1 centimeter (cm) | |
