Converting measurements can often be a tricky endeavor, especially when dealing with different units. One common conversion many encounter is from inches to millimeters. Today, we’re going to focus on how to convert 1 1/4 inches to millimeters. Let’s embark on this journey of understanding the conversion process while making it as simple and clear as possible!

Understanding the Basics: Inches and Millimeters

Before we dive into the conversion specifics, let's clarify what inches and millimeters are:

  • Inches (in) are a unit of length in the imperial system, commonly used in the United States and other countries that have not fully adopted the metric system.
  • Millimeters (mm), on the other hand, are a metric unit of length and are used globally, especially in scientific contexts.

Conversion Factor Between Inches and Millimeters

To convert inches to millimeters, one must know the basic conversion factor:

1 inch = 25.4 mm

Calculating 1 1/4 Inches to Millimeters

The first step in converting 1 1/4 inches to millimeters is to convert the mixed number into an improper fraction or a decimal.

1 1/4 inches can be expressed in decimal form as follows:

1 + 1/4 = 1.25 inches

Now, using our conversion factor:

1.25 inches × 25.4 mm/inch = 31.75 mm
