Sometimes, you have to convert between different units of measure. Millimeters (mm) are metric, while inches (in) are an imperial unit used in the United States. You might need to convert between them for engineering or do-it-yourself (DIY) projects.
This article explains how to convert 63.5 mm to inches.
Understanding Millimeters and Inches
Before we convert 63.5 mm to inches, let’s take a quick look at what millimeters and inches actually are.
What’s a Millimeter?
A millimeter (mm) is a unit of length in the metric system, which is used around the world. There are 1000 millimeters in a meter.
What’s an Inch?
An inch (in) is a unit of length commonly used in the United States. There are 12 inches in a foot.
The origin of the inch isn’t definitively known, but some believe it’s based on the width of a human thumb.
The conversion formula and other information
The key to making this conversion is knowing that 1 inch equals 25.4 millimeters.
So, to convert from millimeters to inches, you divide the number of millimeters by 25.4. Here’s the formula:
Inches = Millimeters / 25.4
If you want to do it the other way around, you can also use the approximate conversion factor of 1 millimeter ≈ 0.03937 inches. The formula would look like this:
Inches = Millimeters 0.03937
Converting 63.5 mm to Inches: A Step-by-Step Guide
So, you want to convert 63.5 millimeters to inches? Here’s how to do it:
- Start with what you know: 63.5 mm.
- Remember the formula: inches = 63.5 mm / 25.4 (or, if you prefer, inches = 63.5 mm 0.03937).
- Do the math: 63.5 / 25.4 = 2.5 inches.
- There you have it! 63.5 mm is equal to 2.5 inches.
Easy peasy!
Practical applications of millimeter to inch conversion
Converting millimeters to inches is super common in fields like engineering, manufacturing, and construction. You might need to make the conversion to ensure the parts you’re using are the right size.
For example, say you’re working on a project where you need a part that’s 63.5 mm long. But the space where that part needs to fit is measured in inches. Converting 63.5 mm to inches allows you to quickly determine if the part will fit properly.
In these types of fields, it’s important to be as precise as possible.
Frequently Asked Questions
