FPS (foot-pound-second) is a unit of energy in the imperial system. It is defined as the work done when a force of one pound is applied over a distance of one foot.
To determine the fps (feet per second) of a projectile with 12 ft-lbs (foot-pounds) of energy, you need to consider the weight of the projectile. This calculation involves using the formula: fps = √(2 * energy / weight). A typical airgun pellet weighing 8.2 grains and fired with 12 ft-lbs of energy would travel at approximately 715 fps.
The number of foot-pounds doesn't directly translate to FPS (feet per second) as other factors like bullet weight, shape, and size also play a role. However, there are online calculators available where you can input the energy in foot-pounds and the bullet weight to get an estimated velocity in FPS.

FPS is the measurement of speed in feet per second. Depending on what kind of bullet you are talking about, bullets can travel as fast as 4400 fps. Here are a few examples: 9mm-about 1050 fps. .45ACP-about 900 fps. 5.56mm-about 2700-3300 fps. .50bmg-about 2900 fps.

Depends on which loading of the cartridge- can be as slow as 2700 fps, or as high as 3700 fps.
