Here’s another example. let’s now imagine that you want to convert 15 mm into inches. Again, you would need to grab the formula:

1 mm = 0.0393700787 in

And:

15 mm = 15 × 0.0393700787 in

15 mm = 0.5905511811 in

As you can see, it is very easy to convert millimeters into inches. Besides, in case you want or need, you can also perform the opposite conversion and convert inches into millimeters.

What Is A Millimeter?

While you may want to simply convert 120mm into inches, is is important that you understand what a millimeter is.

Simply put, a millimeter is a unit of length in the International System of Units (SI). The millimeter is defined in two different ways: as the distance traveled by light in 1/299 792 458 000 of a second or in terms of the meter, where a millimeter is 1/1000 of a meter.

What Is An Inch?

Just like it is important to know what a millimeter is when you are converting 120mm into inches, it is also important to understand what an inch is.

Simply put, an inch is another unit of length. However, it is a unit of length in the US Customary and the Imperial Systems of measurement.

An inch can be simply defined as the equivalent to 25.4 millimeters. You can also state that there are 36 inches in a yard and 12 inches in a foot.

The inch is currently used only in a small number of countries. These include the United States, Canada, and the United Kingdom. You can also see Japan and other countries referring to this unit of length when they want to show the size of display screens, for example.

More About The Millimeters To Inches Conversion

In case you don’t know, millimeters (mm) and inches (in) are a part of the International System of Units and Imperial/ US Customary systems, respectively.

As we already saw, millimeters and inches aren’t very similar in what concerns their size. Nevertheless, these units tend to be used in similar applications.

When you are trying to convert inches to millimeters, you already know that 1 inch is exactly 25.4 millimeters. So, when you are trying to discover the inches from millimeters, you just need to divide the amount of millimeters you are trying to determine by 25.4. On the other hand, when you want to know millimeters from inches, you will need to perform the opposite operation and multiply the inches by 25.4.

The origin of this conversion can be found in the International Yard And Pound Agreement that was signed on July 1, in 1959 by six countries: the United States, South Africa, New Zealand, Australia, Canada, and the United Kingdom. This agreement allowed these countries to establish the exact conversions for mass and length between the metric and imperial systems. Some of the established conversions include:

1 foot = 12 inches

1 yard = 3 feet

So, when we know these conversions, we can immediately state that:

1 yard = 36 inches since 1 yard = 0.9144 meters, according to the agreement.

A Word Of Caution

It is important to notice that 1 millimeter is considerably smaller than 1 inch. We can state that 1 millimeter is about 1/32 of an inch. So, when you are trying to determine fractions of an inch, using this conversion formula may be simpler.

Notice that millimeters and fractions tend to be very used to measure bolts, nuts, wrench sizes, among other hardware. While most countries in the world tend to use millimeters to measure fastening hardware, for example, the United States prefers to use mixed fractions for larger hardware and fractions of an inch for other hardware.

Conclusion

So, no matter if you have inches and want to convert to millimeters or when you have the millimeters and want to convert to inches, you can no do so without any problems. As you could see by the many examples provided, convert 120mm to inches is incredibly easy and you can do it on your own without any problems.
