FAQ/ Information
The inch (inch in English, symbols: in or double plica (?) ) is a unit of length used in the imperial system of measurements. One inch equals 2.54 centimeters or 25.4 millimeters.
The inch is widely used by Anglophone nations. However, in the International System of Units (SI), the use of the inch is not recommended, as defined in chapter 4.2 of its 8th edition published by the BIPM (Bureau International des Poids et Mesures).
The international standard ISO 80000-4, whose current Brazilian version is ABNT NBR ISO 80000-4:2007 (Quantities and Units. Part 4: Mechanical), also denies non-recommended units to attachments at the end of the standard, being the inch between them.
The inch originates from the ancient age where Romans measured the length with their own thumb. It is the width of a regular human thumb, measured at the base of the nail, which, in an adult human, is approximately 2.5 cm. There have also been attempts to link the measurement with the distance between the tip of the thumb and the first joint; however, this is usually speculative.
Currently, the inch is defined according to the meter, which is the SI's unit of length. In 1959, there was an agreement between the United States, the United Kingdom, Canada, Australia, New Zealand and South Africa to establish the international pound and yard through traceability to the SI, which at the time was known as the Metric System. Because the Metric System (SI) is much more developed and accurate, the agreement defined that 1 inch equals exactly 25.4 mm, i.e. 0.0254 m.

The international standard symbol for inch is in (see ISO 80000-4). Sometimes the unit inch is also represented by a double plica (e.g. 30? = 30 in). Similarly, the foot (unit) is represented by a plica, and then 6? 2? means 6 feet and 2 inches, which measure 1,8796 m.
There is no space between the number and the poles, contrary to what happens between the number and the in symbol.
However, due to lack of knowledge or technical difficulties, the double quote is sometimes mistakenly represented by curved quotes () or by ASCII quotation marks ('); likewise, the duplicate (?) is sometimes mistakenly represented by an apostrophe () or an ASCII apostrophe (').

Figure 1 representation of a mixed fraction and its fractional correspondent
The fraction is a way of representing a part of a whole. It is a portion of a unit that has been divided into equal parts. A well-known example is a pizza cut into eight pieces or the fractional inch.
Generally, the fraction is represented by a pair of vertically aligned numbers separated by a dividing line. The number on the line is the numerator and the bottom number is the denominator. The example in figure 1 represents a mixed fraction, which is larger than the unit, in this case, the number of integers is represented to the left of the dividing line (think of an entire pizza plus five pieces).
The denominator expresses how many parts the integer was divided into, in the example in Figure 1 it was divided into eight parts. The numerator expresses how many parts will be considered (five). In this example, we're considering an entire unit and five parts of another that was divided into eight (one and five eighths).
It is also possible to represent an integer in the form of a fraction: 8/8, 2/2, 1/1, 128/128 are expressions of the unit (number one 1). See, in Figure 1, that the distance between 0 and 1 is an integer that is divided into eight eighths. In this way:
1 = 2/2 = 4/4 = 8/8 = 16/16 = 32/32 = 64/64 = 128/128 … (we call it an apparent fraction). It is not recommended, or elegant, to express the whole in this way.
See that 1 5/8 Equals 1 + 5/8 = 8/8 + 5/8 = 13/8 (keep the denominator and add the numerator).
13/8 Is what we call an improper fraction (the numerator value is greater than that of the denominator). Leaving the fraction this way is to set up a trap that will wait for you to fall into it. Always express it in mixed form (1 5/8).
The fraction must be expressed in its simplest possible or irreducible form. We know that 4/8 is the same as 1/2 and we should express the fraction in the form 1/2. Without wanting to gauge anyone: if both the numerator and the denominator are even numbers, it is easy to simplify, the same if both are divisible by three, five … and so on.

Figure 2 inch divided into 16 fractions
Figure 3 measuring an object in fractional inch result: 5/8?
One inch is fractional into two halves which, in turn, are also divided in their means to so successively. This is the progression that the splitting of inch fractions produces: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256, Where each new term represents half of the previous one. (It's important to memorize this numerical progression).
It's a bit anti-intuitive, but a larger number in the denominator decreases the size of the fraction; that's what we call inversely proportional. One way to understand this is to observe that the inch will be divided into a larger number of parts. This way, if you want to decrease the fraction of the inch, go multiplying the denominator by two (1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128), Among other means.
1. Sum of fractions
When the sum of the fractions (the sum of the value of the neon to the scale, for example) has an even numerator, divide both by two until an odd number remains irreducible fraction (see the importance of memorizing that sequence?). Ex.: 1/8 + 3/8 = 4/8 = 2/4 = 1/2.
Tip: when we add two even numbers or two odd numbers the result will always be an even number, when we add an even number to an odd number the result will always be an odd number.
Another caution is that we can only add fractions whose denominators are equal. You can't add 1/2 to 1/16 unless we convert the fractions to the same denominator. This way 1/2 = 2/4 = 4/8 = 8/16 Which added to 1/16 dá 9/16. It multiplies the numerator and denominator of the largest fraction by two until the denominator is equal to the other.
2. Divide in half
Dividing a fraction in half (determining the radius, for example) is also quite simple. If it is a mixed fraction (1 5/8, for example) convert it into an improper fraction (13/8) and multiply the denominator by two (the half of 1 5/8, which is equivalent to 13/8, is 13/16), if the fraction is proper just multiply the denominator by two straight (half of 3/4 is 3/8; half of 63/64 is 63/128)…
Tip: If in the mixed fraction the integer value is an even number, it is not necessary to convert to an improper fraction, you can also divide the whole number by two.
(ex: half of 2.1/4 is 1.1/8; half of 4.5/8 is 2.5/16)
3. Measuring fractions
And finally, those who work in the decimal system have a habit of counting marks from left to right. This is not how you do it with fractions. We must look at the entire fraction and locate its half (usually the mark is slightly larger than the adjacent ones) and repeat this process until we reach the measure, adding the fractions. Practice leads to the first. However, at the time now, we are generally under pressure.
Tip: Count the number of strokes from one whole inch to the next (usually it's 32 or 64 remember that you're not counting the marks but rather the distance between them). If it's 16 -figure 3- does each distance equal to 1/16? count how many marks there are to the extent that interests you, (the tenth - figure 3) see that the fraction is 10/16; ten is even number, simplify it by dividing both by two until there are odd numbers left in the numerator. The answer is 5/8 -figure 3.

The meter (symbol: m) is the unit of measurement of length of the International System of Units. It is defined as 'the length of the path traveled by light in a vacuum over a time interval of 1/299 792 458 of a second'.
The millimeter is also a unit of length in the Metric System (SI), equivalent to one thousandth of a meter (the base unit of length of the SI). The millimeter, as part of the metric system, is used as a measure of length worldwide. The most notable exception is the United States, where the imperial system is still used in most cases.
The origin of the word metro is the Greek term?????? (metron) which means measure.
The idea of a unified system of measures was first implemented in France at the time of the French Revolution. The existence of different systems of measures was one of the most frequent causes of disputes between traders, citizens and tax collectors. With the unified country, a single currency and a unified national market, there was a strong economic incentive to break with this situation and standardize a system of measures. The constant problem was not only the different units, but mainly the different unit sizes. Rather than simply standardizing the size of existing units, the leaders of the French National Constituent Assembly decided that a completely new system should be adopted.
The French Government made a request to the French Academy of Sciences to create a system of measures based on a non-arbitrary constant. After this request, a group of French researchers, composed of physicists, astronomers and surveyors, began this task, thus defining that the unit of length meter should correspond to a certain fraction of the Earth's circumference and also corresponding to a range of degrees from the meridian. terrestrial.
On June 22, 1799, two prototypes of iridiated platinum, representing the metre and the kilogram, were deposited at the Archives of the Republic in Paris, which are still kept today at the International Bureau of Weights and Measures (Bureau International des Poids et Mesures) in France.
On May 20, 1875, an international treaty known as the Convention du Mčtre (Metro Convention), was signed by 17 states and established the creation of the Bureau International des Poids et Mesures (BIPM), a permanent laboratory and world center for scientific metrology, and the Générale des Poids et mesures (MGPC), which in 1889, in its 1st edition, defined the international metro prototype.
The convention-defined measure, based on the dimensions of the Earth, is equivalent to the tenth millionth part of the quadrant of a terrestrial meridian. However, the growing demand for more precision of the frame and the possibility of its more immediate reproduction led the parameters of the basic unit to be reproduced in the laboratory and compared to another constant value in the universe, which is the speed of electromagnetic propagation. Thus, the tenth millionth part of the quadrant of a terrestrial meridian, measured in the laboratory, corresponds to the linear space traveled by light in a vacuum during a time interval corresponding to 1/299 792 458 of a second, which remains the standard meter.
Note: The total path taken by light in a vacuum in a second is called second light. The adoption of this definition corresponds to setting the speed of light in a vacuum at 299 792 458 m/s.
