How many inches are there in 355 millimeters?
The correct answer and explanation is:
✅ Correct Answer:
355 millimeters is approximately 13.976 inches.
📏 Detailed Explanation (300 words):
To convert millimeters (mm) to inches (in), we use the standard conversion factor:
1 inch = 25.4 millimeters
This means that to convert millimeters to inches, you divide the number of millimeters by 25.4.
🔢 Step-by-Step Conversion:
Given:
355 millimeters
Apply the conversion formula: Inches=355 mm25.4\text{Inches} = \frac{355 \, \text{mm}}{25.4} Inches≈13.976378\text{Inches} \approx 13.976378
Rounded to three decimal places: 13.976 inches\boxed{13.976} \, \text{inches}
📚 Why This Matters:
The metric system (used globally) and the imperial system (used mainly in the U.S.) often need to be converted for consistency in science, engineering, construction, and everyday use. For example, if you’re building something based on metric measurements but using tools or materials marked in inches, accurate conversion ensures compatibility and precision.
🛠 Example in Real Life:
Let’s say you’re buying a 355 mm long metal rod for a DIY project, but your workspace is set up using inches. Knowing that it’s roughly 13.98 inches helps you plan accurately without measuring errors or mismatched parts.
🧠 Final Note:
Always remember:
- To convert mm to inches, divide by 25.4
- To convert inches to mm, multiply by 25.4
This simple formula ensures accuracy in all fields requiring unit conversion, from school assignments to professional engineering tasks.
