    It comes down to the way a force is measured.

    What do the units lbs and lbf mean in english.

    i know lbf means pound force... but what does lbs mean is it poundal...

    oooppps - I was using English definitions not American so got a tourque in there

    LBS is the abbreviation for Pounds Mass. (Eng)

    LBF is the abbreviation for Pounds Force. (US)

    So what can you say is the relationship between them?

    The problem asks for a relationship between "pounds" and "Newtons". Since the Newton IS a unit of force, they can only mean "pounds" as a unit of force: LBF.

    1lbs = how many newton

    What is the equation for Force?

    What is the Mass and what is the acceleration?

    What is the definition for 1 Newton? A Mass , An Acceleration

    Is the force applied by 1 lb always 1lbf?
