Would anyone know how the 12 ft lbs translates into muzzel velocity for a
given calibre of air weapon as this is the figure usually given in specs and
reviews.

------------
It all depends on the weight of the pellet. Muzzle velocity alone is not an
absolute measure of kinetic energy. A .177 pellet can go way faster than a .22
and still be legal.
