A Sectional Density Calculator is a useful tool for calculating the sectional density of a projectile. Sectional density is a measure of a projectile's ability to overcome air resistance in flight. It is a crucial factor in ballistics and helps in understanding the penetration capabilities of the projectile. This calculator requires the diameter and weight of the projectile to compute its sectional density.
Purpose and Functionality
The primary purpose of the Sectional Density Calculator is to provide a quick and accurate way to determine the sectional density of a projectile. This metric is important for hunters, shooters, and anyone involved in ballistics to assess the performance of different projectiles. The calculator simplifies the process by automating the necessary conversions and calculations, allowing users to obtain results quickly without manual computation.
Step-by-Step Examples
To understand how the calculator works, let's go through a step-by-step example.
Example:
Let's calculate the sectional density of a projectile with the following specifications:
- Diameter: 0.308 inches
- Weight: 180 grains
- Convert Weight to Pounds:
- Weight (lbs) = Weight (grains) / 7000
- Weight (lbs) = 180 / 7000
- Weight (lbs) = 0.02571
- Calculate Sectional Density:
- SD = Weight (lbs) / (Diameter)^2
- SD = 0.02571 / (0.308)^2
- SD = 0.02571 / 0.094864
- SD = 0.2709
Therefore, the sectional density of the projectile is approximately 0.2709.

| Weight (in grains) | 180 |
| Weight (in pounds) | 0.02571 |
| Sectional Density (SD) | 0.2709 |
Conclusion
The Sectional Density Calculator is a valuable tool for anyone involved in ballistics. It simplifies the process of calculating sectional density by providing a quick and accurate result based on the input values of diameter and weight. Understanding sectional density is crucial for evaluating the performance and penetration capabilities of different projectiles. By using this calculator, users can make informed decisions about their projectile choices, enhancing their shooting and hunting experiences.
