# What is ft lbs of energy?

## What is ft lbs of energy?

The foot-pound force (symbol: ft⋅lbf, ft⋅lbf, or ft⋅lb) is a unit of work or energy in the engineering and gravitational systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot.

## How much do 22 pellets drop?

It has about 50 inches of drop at 100 yards when using a single point zero. Doubling the BC to 0.020 (blue line) cuts the drop about in half to 25 inches, but after that the reduction in drop becomes much less as you increase the BC.

How is FPE calculated?

To calculate muzzle energy, or Foot-Pounds Equivalent (FPE), you need to know the mass of the item being moved and the velocity it will be moving. This is the formula for kinetic (moving) energy and is calculated as K.E. = 1/2*M*V2 where M is mass and V is velocity.

Is 400 ft lbs of torque a lot?

Having 400 pounds of torque down low means you have more horsepower down low. Having 400 pounds of torque up high means you have even more horsepower then you had down low.

### How many ft lbs is 1 HP?

1 horsepower (hp) = 550.00 foot pounds per second (ft-lb/sec)

### How fast is a BB gun in mph?

BB guns can fire at speeds of up to 550 feet per second. Pellet guns can be even more powerful with speeds approaching 1,000 feet per second. Those are mildly interesting figures, but they mean little without some point of reference for injury.

What is FPE?

FPE is foot pounds of energy. It is calculated when you take the velocity and weight of the pellet into consideration. (click here for a handy calculator!). It is a much better measure of the effectiveness of an airgun, but still not at all conclusive.

How to calculate 12 ft lbs into FPS?

So it’s 12.7 ft/lbs times 450240 divide by 18 grains (just say) , then the square root of that number = 563.62 feet per second. yes i used a calculator. Thanks for that guys ! have you tested you gun? grain is everything. however in .177 12ft is 805 fps on average and in MANS calabre its around 605.

## How to convert ft / lbs to feet per second?

To convert from ft/lbs to fps Take the energy (ft/lbs) times (x) the constant (450240) and divide by the weight of the pellet in grains. The square root of that number is your feet per second. So in your case it’s 12.7 ft/lbs times 450240 divide by 18 grains, then the square root of that number = 563.62 feet per second. yes i used a calculator.

## How tall is 12 ft in ft and in?

The square root of that number is your feet per second. So it’s 12.7 ft/lbs times 450240 divide by 18 grains (just say) , then the square root of that number = 563.62 feet per second. yes i used a calculator. Thanks for that guys ! have you tested you gun? Jambaman likes this.

How to calculate the FPS of a pellet?

Have a look at this site – have a play with the various pellet weights and it will give you an idea of FPS versus ft/lbs versus pellet weight! Take the energy (ft/lbs) times (x) the constant (450240) and divide by the weight of the pellet in grains. The square root of that number is your feet per second.
