Definition: An inch symbol: in is a unit of length in the imperial and US customary systems of measurement. An inch was defined to be equivalent to exactly There are 12 inches in a foot and 36 inches in a yard.

There have been a number of different standards for the inch in the past, with the current definition being based on the international yard. One of the earliest definitions of the inch was based on barleycorns, where an inch was equal to the length of three grains of dry, round barley placed end-to-end.

Another version of the inch is also believed to have been derived from the width of a human thumb, where the length was obtained from averaging the width of three thumbs: a small, a medium, and a large one. The online converter has very simple interface and will help us quickly convert our inches.

The online inch converter has an adaptive shape for different devices and therefore for monitors it looks like the left and right input fields but on tablets and mobile phones it looks like the top and bottom input fields. If you want convert any inch values, you must only enter required value in the left or top input field and automatically you get the result in the right or bottom field.

Under each field you see a more detailed result of the calculation and the coefficient of Calculator for converting units of measurement works symmetrically in both directions. If you enter any value in any field, you will get the result in the opposite field. Clicking on the arrow icons between the input fields you can swap the fields and perform other calculations. We are all made for easily converting any values between inches and mm.

Results conversion inches into millimeters. If you came to this page, you already see the result work of the online calculator. In the left or top field you see the value of "in" on the right or bottom box you see the value of result is equal to We have briefly reviewed how to use the unit Converter on this page, but this is only part of the features of the page service.

We made an interesting possibility to compute all possible values for units of measure in the lower tables. These tables are used to convert basic units of measurement: Metric conversion chart, US Survey conversion chart, International conversion chart, Astronomical conversion chart. Please, find these 4 tables at the bottom of this page they have the headers: All conversions of inches in the Metric System Units All conversions of inches in the US Survey Units All conversions of inches in the International Units All conversions of inches in the Astronomical Units If you enter a test number in any field of web calculator field of inches or millimeters it doesn't matter , for example as it is now, you not only get the result in Without doing your own search and making the transition to other pages of the website, you can use our conversion tables to calculate all the possible results for main units.

Try delete and again entering into the calculator a value of inches and you will see that all the conversion results in the lower tables will are recalculated for in. The calculated data in the conversions tables change dynamically and all transformations are performed synchronously with converting inches in the page calculator.

How many millimeters are in inches? To answer this question, we start with a brief definition of inch and millimeter, and their purpose. The inch and millimeter units of length which can be converted one to another using a conversion factor which is equal to This coefficient answers the question how many millimeters are equivalent to one inch.

The value of this multiplier determines the basic value to calculate all other lengths, sizes and other transformations for these units inch and millimeter , it is enough to know the value, i. Knowing the number of millimeters in one inch by simple multiplication we can calculate any values.

Let's do a simple calculation using the multiplication:. We have already seen how to convert these two values and how change inches to millimeters. So in summary, you can write all possible results that have the same meaning.

In the calculations for inches and millimeters, we will use the formula presented below that would quickly get the desired result. That is, you need to remember that 1 inch is equal For instance, you may find a device that is mm thick. That is why you need a chart or calculator to make the conversion.

Once you know how to convert mm to inches, you can use the same procedure for 20 mm, 30 mm and so on. As to which method is the most effective, the choice is up to you. For many, a calculator is the most efficient. No need to figure whether to divide or multiply what figure. Just type mm and you get results. The importance of having a chart or calculator cannot be overstated. You may know that 1 mm is equal to 0. You may also know that you can divide mm by But that is difficult to do manually.

Rather than manual figuring, our options here are faster. To answer that question right off, millimeters is equivalent to If you know how to find the inch equivalent of mm, you will find it easier to do with other measurements as well. For your reference, however, we have here the other common mm figures used for other measurements. When the metric system was established, the goal was to make it the universal means of measuring.

Even then the experts knew it would be more practical to use the same measuring units. However, that has not happened yet.
