Converting imperial measurements to metric can be tricky, especially when dealing with fractions. This article will clearly explain how to convert 1 3/8 inches to its metric equivalent in millimeters and centimeters, providing the calculations and context for understanding the process.

Understanding the Conversion Factor

The fundamental conversion factor between inches and millimeters is approximately 25.4 millimeters per inch. This means that one inch is equal to 25.4 millimeters. We'll use this factor to accurately convert our measurement.

Step-by-Step Conversion of 1 3/8 Inches

  1. Convert the fraction to a decimal: The fraction 3/8 is equal to 0.375.

  2. Add the whole number: Adding the whole number (1) to the decimal gives us 1.375 inches.

  3. Multiply by the conversion factor: Multiply 1.375 inches by 25.4 millimeters/inch:

    1.375 inches * 25.4 mm/inch = 34.925 millimeters

Therefore, 1 3/8 inches is equal to 34.925 millimeters.

Expressing the Result in Centimeters

Since there are 10 millimeters in a centimeter, we can easily convert the result to centimeters:

34.925 millimeters / 10 mm/cm = 3.4925 centimeters

So, 1 3/8 inches is also equal to 3.4925 centimeters.

Rounding for Practical Purposes
