## About Foot Pounds of Energy Calculator (Formula)

A Foot Pounds of Energy Calculator is a tool that allows you to calculate the amount of energy a bullet has based on its mass in grains and its speed in feet per minute.

The formula used to calculate the energy is:

**E = M * BS^2 / 450437**

Where:

- E is the Foot Pounds of Energy (foot-pounds)
- M is the mass of the bullet in grains
- BS is the bullet speed in feet per minute.

This formula is used to calculate the energy of a bullet. It’s useful for people who want to know the energy of a bullet, for example, for hunting or shooting sports. The Foot Pounds of Energy Calculator can be used to calculate the energy based on the mass and speed of the bullet, it can be useful for hunters, shooters, and ballistics enthusiasts.
