**1″ (Inch, in)
** - English
inch is a value for measuring lengths and distances, heights and widths and etc.
One inch is equal to 25.4 millimeters.

On this page we consider in detail all variants for convert 1 inch to millimeters and all opportunities how to convert inches with usage comprehensive examples, related charts and conversion tables for inches. Here you will find all the ways for calculating and converting inches in mm and back. If you want to know how many millimeters are in 1 inch you can obtain the answer in several ways:

- convert 1 inch using the online conversion on this page;
- calculate 1 inch using calculator InchPro from our software collection for offline converting units;
- apply arithmetic calculations and conversions for 1 inch outlined in this article.

To indicate inches, we will use the abbreviation "in" to
indicate millimeters we
will use the
abbreviation "mm". All options to convert "in" to
"mm" we will look more detail in individual
topics below. So, we're starting explore all avenues of transformation
**one** inch and
conversions between inches and millimeters.

To convert 1 inch into millimeters we consider using the online
converter on the web page. 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 25.4 which is used in the
calculations.
The big green string, under the input fields - **"1 Inch
= 25.4 Millimeters"** further enhances and shows final result of
the conversion. 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 1 inch into millimeters.
1 inch to "mm" is equal to 25.4 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 1 "in" on the right (or bottom) box you see the value of
result is equal to
25.4 "mm". Write briefly: **1 "in" = 25.4
"mm"**

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 1 inch in the Metric System Units****All conversions of 1 inch in the US Survey Units****All conversions of 1 inch in the International Units****All conversions of 1 inch in the Astronomical Units**

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 25.4. 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.e. to
remember that **1 inch = 25.4 (mm)**.
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:

**1″ × 25.4 = 25.4
(mm)**

Thus it is seen that after multiplying by the coefficient we get the following relationship:

**1 Inch = 25.4 Millimeters**

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.

**
1 inch to mm = 25.4 mm
1 inch in mm = 25.4 mm
1 inch into mm = 25.4 mm
1 in = 25.4 mm
1″ = 25.4 mm
1″ is 25.4 mm
one inch = 25.4 mm**

To convert 1 inch into millimeters we can use many ways:

- calculation using the formula;
- calculation using the proportions;
- calculation using the online converter of the current page;
- calculation using the offline calculator "InchPro Decimal".

In the calculations for inches and millimeters, we will use the formula presented below that would quickly get the desired result.

Y (in) × 25.4 = X (mm) Y - value of inches X - result in millimeters

That is, you need to remember that 1 inch is equal 25.4 millimeters, and when converting inches just multiply the number of inches (in this case 1 inch) by a factor of 25.4. For example, we transform the set of values 1.0″, 2.0″, 3.0″, 4.0″, 5.0″ into millimeters and get the result in the following examples:

1.0 (in) × 25.4 = 25.4 (mm) 2.0 (in) × 25.4 = 50.8 (mm) 3.0 (in) × 25.4 = 76.2 (mm) 4.0 (in) × 25.4 = 101.6 (mm) 5.0 (in) × 25.4 = 127.0 (mm)

In all variants we multiplied the all inches in range from 1.0″ to 5.0″ with the same ratio of 25.4 and got the correct results in calculations.

To calculate the proportions you need to know the reference value in millimeters for 1 inch and according to the rules of arithmetic we can calculate any value in millimeters for any length in inches. See the next examples. We form the proportion for 3 values our inches 1.0″, 2.0″, 3.0″ and calculate results values in millimeters:

1 (in) — 25.4 (mm) 1.0 (in) — X (mm) Solve the above proportion for X to obtain: X = 1.0(in) × 25.4(mm) ÷ 1(in) = 25.4(mm)

1 (in) — 25.4 (mm) 2.0 (in) — X (mm) Solve the above proportion for X to obtain: X = 2.0(in) × 25.4(mm) ÷ 1(in) = 50.8(mm)

1 (in) — 25.4 (mm) 3.0 (in) — X (mm) Solve the above proportion for X to obtain: X = 3.0(in) × 25.4(mm) ÷ 1(in) = 76.2(mm)

All proportions used reference value 1 inch = 25.4 mm

You can use our basic universal online converter on the current web page and convert any your length dimensions and distances between inches and millimeters in any directions free and fast.

Currently, the field for inches contains the number 1 (in) you can change it. Just enter any number into field for inches (for example any value from our set: 2.0, 3.0, 4.0, 5.0 inches or any other value) and get the fast result into field for millimeters. How to use the inch online calculator you can more detail read at this link manual for the calculator.

For example, we take the 16 values into inches and will try to calculate the result values in millimeters. Also, we will use the web calculator (you can find it at the top of this page). In the set up a table in the left margin we write the value in inches in the right margin you see the values that you should obtain after calculation. You can check it right now, without leaving the site and make sure that the calculator works correctly and quickly. In all calculations, we used the ratio 25.4 which helps us to get the desired values of computation results in millimeters. Please, see the results in the next table:

Please, also see the screenshots for acquaintance.

Many people can hardly imagine the relationship between inch and millimeter. In this picture, you can clearly see the ratio of these quantities to understand them in real life. The ratio of the lengths of the segments is retained on screens with any resolution as for large monitors as well as for small mobile devices.

The graph shows the relative values the inches in the form of rectangular segments of different lengths and colors. As well as the visual representation of 1 (in) with the reference value in millimeters.

The graphs of the relationship between inches and millimeters are expressed in the following colours:

- Green is the original length or distance in inches;
- Blue color is the scale in inches;
- Yellow color is the scale in millimeters.
