Whether you’re in engineering, manufacturing, or just tackling a DIY project at home, chances are you’ll run into situations where you need to convert between millimeters (mm) and inches (in). Accurate conversions are a must for many jobs.
This article is all about converting 98mm to inches. We’ll look at the definitions of each unit, the conversion formula, and practical examples to help you understand how to convert one to the other.
Defining Millimeters and Inches
Let’s take a look at the units we’re working with here.
Millimeter (mm)
A millimeter is a unit of length in the International System of Units (SI), the modern form of the metric system. A meter is equal to 1,000 millimeters.
Inch (in)
An inch is a unit of length in the imperial and U.S. customary measurement systems. There are 12 inches in a foot, and 36 inches in a yard.
An inch is equivalent to exactly 25.4 millimeters.
The conversion formula
The key to converting between millimeters and inches is remembering this: one inch equals 25.4 millimeters. That’s it. Once you know that, you can easily convert any measurement from one system to the other.
To convert millimeters to inches, use this formula:
Inches = Millimeters / 25.4
To convert inches to millimeters, use this formula:
Millimeters = Inches 25.4
If you want to quickly approximate, just remember that 100 millimeters is about 4 inches.
Converting 98mm to Inches: Step-by-Step
Ready to do the math? Here’s how to convert 98 millimeters into inches:
- Remember the formula: inches = mm / 25.4
- Plug in 98mm: inches = 98 / 25.4
- Calculate: 98mm = 3.858 inches (approximately)
Depending on what you’re measuring, you might want to round that number. 98mm is about 3.86 inches if you round to the nearest hundredth and about 3.9 inches if you round to the nearest tenth.
Practical Applications and Examples
So, you know how to convert 98 mm to inches. But when would you ever need to do that?
Engineering and Manufacturing
In engineering, drawings and specs often use both millimeters and inches. So, it’s important to be able to convert accurately to ensure parts fit together correctly.
For example, if a component needs to be exactly 98 mm long, what is that length in inches for a supplier in the United States?
Everyday Use
You might need to convert millimeters to inches when you’re buying furniture from overseas or trying to figure out the size of a screen.
For instance, if a picture frame is advertised as 98 mm wide, how wide is that in inches so you can visualize the size?
3D Printing
3D printing and design also rely on both millimeters and inches. Just like in engineering, accurate conversions are critical so the parts fit together as intended.
Conversion Charts and Tools
Sometimes, you just need a quick estimate. Conversion charts can give you that estimate at a glance. However, charts aren’t always precise.
If you need a precise conversion, use an online tool or calculator. They do the math for you, so you don’t have to worry about making a mistake. Of course, you need to have access to a phone, tablet, or computer to use an online tool.

Frequently Asked Questions
What size is 98mm in inches?
98 millimeters is approximately equal to 3.86 inches. To get this conversion, you divide the number of millimeters (98) by 25.4, which is the number of millimeters in one inch.
Is 100 mm the same as 4 inches?
Not quite, but it’s close! 100 millimeters is equivalent to approximately 3.94 inches. So, it’s just a little bit shy of being exactly 4 inches. For most practical purposes, you could round it up, but for precise measurements, it’s important to use the exact conversion.
Is 10 mm the same as 1 inch?
Definitely not! 10 millimeters is much smaller than one inch. In fact, 1 inch is equal to 25.4 millimeters. So, 10 mm is less than half an inch (approximately 0.39 inches, to be exact).
How do you convert mm radius to inches?
Converting a radius from millimeters to inches is the same process as converting any other length measurement. You simply divide the radius in millimeters by 25.4 (the number of millimeters in an inch). So, a radius of, say, 50mm would be approximately 1.97 inches (50 / 25.4 = 1.9685).
Wrapping Up
Okay, let’s recap. We’ve seen that millimeters (mm) and inches are different units of measurement. We’ve used the conversion formula (1 mm = 0.0393701 inches) to learn that 98 mm is equal to 3.858 inches.
Accurate unit conversions are super important in fields like engineering, construction, and even cooking! Hopefully, you can use this information and the converter we’ve provided for your own needs.
In our increasingly global world, understanding both metric and imperial units is a valuable skill. It helps us communicate effectively and avoid costly errors.
