Converting between measurement systems is something most people have to do at some point. It’s especially common to need to convert between metric (millimeters) and imperial (inches).
So, how do you convert 220 mm to in? Well, 220 mm is approximately 8.66 inches. This article explains exactly how to do that conversion.
Understanding Millimeters and Inches
Before converting, let’s get clear on what millimeters and inches actually are.
What is a Millimeter (mm)?
A millimeter is a unit of length in the International System of Units, or SI. A millimeter is a tiny measurement, equalling 1/1000 of a meter.
What is an Inch (in)?
An inch is a unit of length in the imperial and US customary systems. The inch has been used as a unit of measurement for centuries. One inch is exactly equal to 25.4 millimeters.
How to convert 220 mm to inches
The formula to convert millimeters to inches is simple:
inches = millimeters ÷ 25.4
So, to convert 220 mm to inches, the equation looks like this:
inches = 220 mm ÷ 25.4
Therefore, 220 mm is equal to 8.6614173228 inches. For most practical purposes, you can round that to 8.66 inches.
Alternatively, you can use this formula: [in] = 220 0.0393700787
Practical Applications and Tools
When do you need to convert millimeters to inches? Lots of situations call for it — engineering, construction, design, and even arts and crafts. If you’re specifying the dimensions for parts manufacturing, you’ll definitely need to be able to switch back and forth between metric and U.S. customary units.
Luckily, there are plenty of online millimeter-to-inch conversion calculators that can do the math for you. Just type in the number of millimeters, click a button, and voila! you’ve got inches. You can also find handy conversion charts online or in books.
Sometimes, you’ll need to convert to fractional inches. For example, 8.6614173228 inches might need to be expressed as 8 and 11/16 inches. To do this, you’d round to the nearest 1/16th of an inch.
Final Thoughts
So, to recap, 220 millimeters is about 8.66 inches. It’s useful to understand how to convert between metric and imperial units, especially if you work in a technical field or travel internationally.
