It’s easy to convert measurements in millimeters to inches. The unit of measurement, mm, must be multiplied by 0.039 to equal inches.

Thus, 50 must be multiplied by 0.03toto translate 50 mm to inches, for instance.

Consequently, 50 mm is 1.95 inches (50 x 0.039).

Consider that you have a 40 mm long, tiny ruler.

Here is the formula if you wish to convert its measurement into inches.

40 x 0.039 equals 1.56 inches when converting 40 mm to inches.

Typically, millimeters are used to measure items that need precise measurements. Consider a 1200 mm lens as an example.

How to convert it to inches is shown below.

1200 X 0.039 equals 46.8 inches when converting 1200 mm to inches.

About Mm ~ Millimeter Definition: 

In the International System of Units (SI), a millimeter (abbreviated as mm) is a unit of length.

It is defined as the distance traveled by light in 1/299 792 458 000 of a second, or 1/1000 of a meter, in terms of the meter.


One of the numerous metric prefixes is milli. In this example, the meter, representsone-thousandthh of the base unit.

The definition of a meter has evolved through time, and the one in use today is based on the distance that light can travel in a certain length of time.

However, the connection between the millimeter and the meter remains constant.

The length of a prototype meter bar served as the basis for the metbefore to this specification.

Due to changes made to the definition of a second in 2019, the meter has been redefined.

Inch definition

An inch is a unit of length in the imperial and US customary systems of measurement (symbol: in).

In 1959, an inch’s definition was precisely 25.4 millimeters. 12 inches make up a foot, and 36 inches make up a yard.


The Latin unit “uncia”—equivalent to “one-twelfth” of a Roman foot—is where the word “inch” comes from.

The present definition of the inch is based on the international yard, while there have previously been a variety of other definitions for the unit.

One of the oldest definitions of the inch was based on barleycorns, where three dried, spherical grains of barley were laid end to end to measure one inch.

Another theory holds that the width of a human thumb, where the length was determined by averaging the width of three thumbs – a little, a medium, and a big one – is where the inch originated.

Present usage: The United States, Canada, and the United Kingdom are where the inch is most often used.

In Japan (as well as other nations), it is sometimes usabout to electrical components, such as the size of display panels.

Popular Length Unit Conversions ~ Difference between Mm and Inches

Here are a few examples of how millimeters and inches vary.

Mm Inches

One of the most compact units used to measure length in the metric system is the millimeter.

Both the imperial and American customary systems of measuring length use the term inch.

One-thousandth of a meter is equal to one millimeter. One inch is equal to one-thirty-sixth of a yard and one-twelfth of a foot.

1 inch equals 25.3 mm1 mm equals 0.039 inches.

The millimeter is used to measure paper widths, tumor sizes, and wavelengths. Radial tire sizes, clothing sizes, and gadget screen sizes are all often measured in inches.

The majority of nations, including the UK, Canada, India, Russia, Germany, and Japan, use the metrics system and hence utilize mm.

While inches are traditionally utilized in the USA, they are increasingly often employed to measure device screen sizes in nations like Japan, Korea, and India.

Smaller areas may be measured using either millimeters or inches. While mm and the metric systemise more widely used in nations like the UK, Canada, India, and others, inches are more prevalent in the USA.
