What is a Millimeter?
Before we dive into the conversion, let’s take a quick look at what a millimeter actually is. A millimeter is a unit of length in the metric system, which is used around the world. It’s quite a small measurement — in fact, 1 millimeter equals one-thousandth of a meter (0.001 meters).
To put it into perspective, a grain of sand is about 0.5mm, so 22mm would be something much larger, like the width of a standard button or the thickness of a medium-sized coin.
Understanding the Inch
On the other hand, inches are part of the imperial system, which is most commonly used in the United States and the UK for everyday measurements. One inch equals 2.54 centimeters or 25.4 millimeters. In terms of size, an inch is roughly the length of the first joint of your thumb.
Why Convert Millimeters to Inches?
Sometimes, products or dimensions are provided in millimeters when you’re more familiar with inches. For instance, if you’re buying a 22mm wrench but need to compare it with other tools you have that are measured in inches, conversion is essential to make sure it matches.
How to Convert 22mm to Inches
Now that we understand the basics, let’s get into the actual conversion from 22mm to inches. The formula for converting millimeters to inches is:
Inches=Millimeters25.4\text{Inches} = \frac{\text{Millimeters}}{25.4}Inches=25.4Millimeters
Using this formula, let’s calculate how many inches are in 22mm:2225.4≈0.866 inches\frac{22}{25.4} \approx 0.866 \text{ inches}25.422≈0.866 inches
So, 22mm is approximately 0.866 inches.
Quick Mental Math Trick
If you don’t have a calculator handy, there’s a quick trick you can use to estimate the conversion. Since 1 inch is about 25.4mm, you can remember that 20mm is roughly 0.79 inches.
