How do you convert pounds into foot pounds?

Answer 1

First, see the LINK below to learn what a foot-pound is, then read as follows:

So as you can see, you cannot convert pounds to foot pounds.

The magnitude of a torque is equal to the magnitude of the applied force multiplied by the distance between the object's axis of rotation and the point where the force is applied.

That means that one foot-pound of torque is a force of one pound applied one foot from the object's axis of rotation.

So if the weight were one foot from the axis, you could say that one foot-pound is equal to one pound. But... Only if the weight was perpendicular to the line from the axis to where the weight was located. Torque is a "turning" force and weight is a "linear" force.

Hope that was helpful.
