How to Use a Conversion Chart:

1. Find the Chart: Look for a chart that lists millimeters (mm) and inches (in).

2. Locate 30.5 mm: Many charts will list common measurements; if 30.5 mm isn't listed, find the closest number (like 30 or 35 mm).

3. Interpolate: If the exact value isn't available, you can interpolate between two known values:

   • For example, if 30 mm = 1.1811 inches and 35 mm = 1.378 inches, 30.5 mm would be:

   [ \frac{1.378 - 1.1811}{5} \times 0.5 + 1.1811 \approx 1.27955 \text{ inches} ]

4. Cross-Reference: It’s helpful to have a few sources or conversion charts to check your result.
