lb=mass and ft=length
N=force and m=length
you cannot convert it.

inconsistent units

inconsistent units????

than how can be torque in Nm or Lb-ft ?????

I disagree with the second poster. In the foot-pound system, the pound is misused as both a unit of mass and force.
(When the engineering distinction must be made, either slugs are invented for mass, or poundals for force, not both).

Convert the pound to newtons and the foot to meters, but the result is 1 ft-lbf = 1.355 818 Nm. (lbf being pound force)

(or use the converter that is part of this site)

technically, lbs are a unit of force, as it is the force of gravity on objects. This is why if you were to move to say, Mercury, you would weigh a lot less in lbs (because it is a unit of force) than you would here, yet you would still have the same mass.

Just to confirm what's already been said, the pound is a unit of weight/force (the word "weight" is an abbreviation of "force of gravity"), and the newton is also a unit of force.
