Step 1:I'll solve this unit conversion problem step by step:
Step 2:: Recall the conversion factor between millimeters and inches
The standard conversion is: 1 inch = 25.4 millimeters
Step 3:: Set up the conversion calculation
\frac{102 \text{ mm}}{1} \times \frac{1 \text{ in}}{25.4 \text{ mm}}
Step 4:: Perform the calculation
102 \div 25.4 = 4.015748 \text{ in}
Step 5:: Round to a reasonable number of significant figures
Since the original measurement (102 mm) has 3 significant figures, we'll round our answer to 3 significant figures.
Final Answer
Key points: - Used direct conversion factor - Divided 102 by 25.4 - Rounded to 3 significant figures - Maintained proper units throughout calculation
