## Decimals to inches

In metalworking workshops from countries that have adopted the International System, as Brazil, country of professor Stefanelli, in general, the easiest way to produce parts that were designed in fractional inch is to convert the measurements in inch to millimeter. After all, machines were designed to work in the international system. However, it is not uncommon to have in our hands a tool in inch and a part or tool for measuring. What do you do? The fraction is a way of representing a part of a whole. It is a portion of a unit which was divided into equal parts. A well known example is a pizza sliced into eight pieces or the fractional inch. Generally, the fraction is represented by a pair of numbers aligned in the vertical and separator by a line divider. The denominator express in how many parts the whole is divided. In the example of Figure 1 it was divided into eight parts. The numerator express how many shares will be considered five. It is also possible to represent a whole number in fraction form. See, in Figure 1, the distance between 0 and 1 is a whole that is divided into eight eighths. It is not recommended, or elegant, to express the whole number this way. Keeping the fraction like this is a kind of trap armed against you. The fraction must be expressed in its simplest possible form or irreducible. No intention to make someone decorate this: if both the numerator and denominator are even numbers it is possible to simplify. The same if both are divisible by three, five … and so on. A inch is fractioned in two halves that, in its turn, also are divided in its halves and so on successively. It is somewhat counter-intuitive, but a greater number in the denominator decreases the size of the fraction. One way to understand this is to note that the inch is divided into a larger number of parts. When the sum of fractions the sum of the value of the vernier to the scale, for example has an even numerator, go on dividing both by two until only an odd number remains — irreducible fraction see the importance of memorizing that progression? Tip: when summing two even numbers or two odd numbers the result will always be an even number. When summing a even number to an odd one the result will always be an odd number. Another caution is that we can only sum fractions whose denominators are equal. Go on multiplying by two the numerator and denominator until the denominator will be equal to the other. Dividing a fraction by half to determine the radius, for example is also quite simple. And finally, for those who work with decimal system and have the habit to count the marks from left to right.

## How to read inches in fractions

There are two types of scales commonly used on rulers; Fractional and Decimal. Decimal Rulers have graduations or marks which are based on the decimal system such as 0. Decimal Rulers can be based on any measuring system but are usually based on either the English measurement system inches in or the Metric measurement system of millimeters mmcentimeters cm and meters m. Decimal Rulers utilizing inches normally have marks or graduations of 0. In the drawing below, we show a ruler with graduations or marks of 0. Often you will encounter rulers that do not have a legend which identifies what decimal of an inch is utilized on the scale. The ruler below has a legend of which indicates that the smallest graduation or mark is 0. If a ruler has no legend the smallest graduation of an inch will have to be calculated. Simply count the number of spaces between graduations or marks contained within a single inch. We discuss here, Decimal Rulers based on the English measurement system of Inches. Box Syracuse, NY U.

## Decimal to fraction chart

There are two types of scales commonly used on rulers; Fractional and Decimal. Decimal Rulers have graduations or marks which are based on the decimal system such as 0. Most Fractional Rulers are based on the English measuring system where scales are graduated in units of one inch and fractions of an inch. When writing down a distance measured, normally the whole inches are followed by the fractional part of an inch. Note from the drawing that all fractional measurements are always reduced to their lowest common denominator. Often you will encounter rulers that do not have a legend which identifies what fraction of an inch is utilized on the scale. The ruler below has a legend of 32nds. If a ruler has no legend the smallest fraction of an inch will have to be calculated. Simply count the number of spaces between graduations or marks contained within a single inch. Fractional Rulers are more difficult to read than Decimal Rulers and mistakes are easily made. We discuss here, Fractional Rulers based on the English measurement system of Inches.
