What is ballistics?
Embark on a Journey Through the World of Ballistics. Ballistics, the science of projectiles, can be divided into three distinct phases, each with its own focus:
- Internal Ballistics: This stage investigates what happens within the firearm or launcher as a bullet or projectile is fired. It’s all about the initial push that propels the projectile forward.
- External Ballistics: Once the bullet leaves the barrel, it enters the realm of external ballistics. This phase is all about how the projectile interacts with forces like gravity and air resistance during its flight through the air.
- Terminal Ballistics: As the projectile nears its target, terminal ballistics comes into play. This phase examines what happens when the projectile strikes something, whether it’s a bullet hitting a target or a ball colliding with an object. It’s all about understanding the impact on both the projectile and the target.
These subfields collectively provide a comprehensive understanding of ballistics, helping us analyze how projectiles behave in different situations. With our Ballistic Coefficient Calculator, you can measure the ballistic coefficient in no time.
What is the ballistic coefficient?
Discover the Magic of Ballistic Coefficient in External Ballistics: The ballistic coefficient is your key to understanding how objects navigate through the resistance of the air. Imagine you have a projectile with mass ‘m’ in kilograms and a drag coefficient ‘C.’ You can calculate the ballistic coefficient ‘B’ using this formula:
B = m / (C × A)
In this equation, ‘A’ represents the projectile’s cross-sectional area. The units for the ballistic coefficient are either kilograms per square meter (kg/m²) or pounds per square inch (lbs/in²).
Now, let’s dive into the world of ballistics, which features seven distinct mathematical models, known as G1 through G7. Among them, the G1 model is the most widely used, especially for projectiles with flat bases and ogive noses. The G1 ballistic coefficient is the term often used to describe this model’s ballistic performance.

How to calculate the ballistic coefficient using the Ballistic Coefficient Calculator?
To determine the ballistic coefficient, follow these simple steps:
- Step 1: Input the projectile’s mass, denoted as ‘m.’
- Step 2: Provide the cross-sectional area, referred to as ‘A.’
- Step 3: Enter the drag coefficient, ‘C.’
- Step 4: The calculator will generate the ballistic coefficient for you.
Using the ballistic coefficient calculator
Want to find out the ballistic coefficient for a 50-gram spherical projectile with a 13 mm diameter and a drag coefficient of 0.51? We’ve got you covered with a straightforward process.
First, let’s determine the cross-sectional area of the spherical projectile. To do this, you can use the formula:
A = π × D²/ 4 = π × 13²/4 = 132.73 mm²
You can either use this formula or make it even easier by trying our circle area calculator.
Now, let’s find the ballistic coefficient step by step:
Step 1: Input the projectile’s weight, ‘m’ = 50 grams. Step 2: Include the calculated cross-sectional area, ‘A’ = 132.73 mm². Step 3: Enter the drag coefficient, ‘C’ = 0.51. Step 4: The resulting ballistic coefficient for the spherical projectile is:
B = m / (C × A) = 738.645 kg/m² = 1.0506 lbs/in²
So, there you have it – the ballistic coefficient for your spherical projectile is 1.0506 lbs/in². This value tells you that the projectile is low-drag, meaning it experiences less negative acceleration. The higher the ballistic coefficient, the less drag your projectile faces. Now you’re all set to understand the behavior of your projectile with confidence!
Applications of ballistic coefficient
Did you know that the ballistic coefficient plays a crucial role in how objects behave in the air? It’s a key factor in everything from reentry vehicles to long-range ammunition.
For reentry vehicles coming back from space, a lower ballistic coefficient is preferred. This helps them slow down quickly and land gently.
On the other hand, projectiles like Intercontinental Ballistic Missiles (ICBMs) or long-range ammo are intentionally designed with higher ballistic coefficients. This design reduces the impact of crosswinds, enabling them to reach their target swiftly with greater kinetic energy.
Take, for example, the low Earth orbit (LEO) satellite EYESAT-I, with a ballistic coefficient of about 0.072 lbs/in². It’s a small, cube-shaped amateur satellite weighing around 11.8 kg. In contrast, a 0.50 caliber low-drag bullet boasts a higher ballistic coefficient at 1.062 lbs/in².
Understanding the ballistic coefficient is crucial in various fields, from space exploration to ballistics. Explore its impact today!

What is the ballistic coefficient?
The ballistic coefficient, like a projectile’s protective armor in the sky, measures its resistance to air drag. A higher ballistic coefficient means better protection, allowing the object to stay on course and keep its speed over long distances. Take, for instance, the low Earth orbit satellite EYESAT-I, boasting a ballistic coefficient of about 0.072 lbs/in², gliding through the sky with minimal disruption. In contrast, high-velocity bullets are equipped with a high ballistic coefficient to maintain accuracy and speed over extended ranges. Whether you’re exploring space or perfecting your aim, mastering the ballistic coefficient is your key to precision and success in the air.
How do I calculate the ballistic coefficient?
Want to find the ballistic coefficient of an object? It’s easier than you think! Just follow these three simple steps:
