Whether you’re in construction, engineering, or just trying to follow a recipe, knowing how to convert between different units of measurement is a must. Different countries and industries use different systems, so being able to switch from one to another is a pretty valuable skill.
This article will guide you through converting millimeters (mm) to inches (in), with a focus on the specific conversion of 46mm to inches. Millimeters are part of the metric system, while inches are used in the imperial and US customary systems. Let’s dive in and learn how to make this conversion easily!
Understanding Millimeters and Inches
Let’s take a closer look at what millimeters and inches represent as units of measure.
What is a millimeter?
The millimeter (mm) is part of the International System of Units (SI), which is the standard system used in science and engineering. One millimeter is equal to one-thousandth of a meter.
Millimeters are used for precise measurements of small objects, such as the diameter of a screw or the thickness of a coin.
What is an inch?
The inch (in) is a unit of length in both the imperial and US customary systems. Historically, the inch was thought to have been based on the width of a human thumb.
In the United States, inches are commonly used for measuring everything from a person’s height to the size of a TV screen.
Inches are part of a larger system of measurement. There are 12 inches in a foot and 36 inches in a yard.
The conversion factor
The single most important thing to know when converting between millimeters and inches is this: 1 inch equals 25.4 millimeters. This is the rule you’ll use for all conversions.
From that, we can also say that 1 millimeter is about 0.03937 inches. You get that number by dividing 1 by 25.4.
It’s important to make sure you use the right conversion factor. Otherwise, you can’t be sure of an accurate result.
Converting 46mm to Inches: Step-by-Step
Okay, so let’s figure out how to convert 46 millimeters into inches. It’s pretty straightforward.
First, here’s the formula we’ll use: Inches = Millimeters / 25.4
Now, let’s plug in our numbers: Inches = 46 / 25.4
If you do the math, you’ll find that 46 mm is about 1.811 inches.
This is handy if you’re trying to understand the size of something described in millimeters, but you think in inches. For example, if you’re buying a wrench, and the size is listed as 46mm, you now know that’s a little over 1 3/4 inches.
