Converting between millimeters (mm) and inches (in) comes up more often than you might think! It’s important in fields like engineering and manufacturing, but even in everyday life. Ever wonder, “How many inches is 88 mm?” The answer is approximately 3.46 inches.
This guide will provide a comprehensive overview of mm to inch conversion, including definitions, formulas, and why it matters.
What are millimeters and inches?
Before we get into the conversion, let’s take a quick look at what millimeters and inches are.
The millimeter (mm)
A millimeter is a unit of length in the International System of Units, sometimes called the metric system. There are 1,000 millimeters in a meter.
Millimeters are the go-to unit of measure in countries that use the metric system, and they’re also used for many technical applications.
The inch (in)
The inch is a unit of length in the Imperial and U.S. customary systems of measurement. Though its historical definitions have varied, it’s now standardized.
Inches are commonly used in the United States and a few other countries. Historically, the length of an inch was based on the average length of three barleycorns laid end to end, or the width of a human thumb.
How to convert millimeters to inches
The formula you need to know is: 1 inch = 25.4 mm. This is a fixed conversion factor, so it’s always accurate.
To convert millimeters to inches, you divide the number of millimeters by 25.4. So, for 88 mm, the calculation is:
88 mm / 25.4 mm/inch ≈ 3.46457 inches
In most situations, you can round that to 3.46 inches.
