What is a pound-force foot?

It is an imperial energy unit representing work done by a one pound-force acting over one foot displacement.

Why convert pound-force foot to thermochemical calorie?

To compare mechanical energy with heat energy values in historical or thermochemical contexts.

Is the thermochemical calorie still commonly used?

No, it has been largely replaced by the joule, but it remains important in older scientific literature.
