James - Nothing except it's just my way of expressing FT LBS.. which could also be expressed as energy , 5 ft lbs=
6.7791 joules, or .691275 KG per meter.


Completely off topic, but Torque and Energy are not even remotely the same thing. Yes, they are expressed in the same units, but I'll leave it as an exercise for the reader to figure out how they are not the same thing.

As for the moon and whether it is planet or a moon ... it is purely a semantics issue and I am not much interested in semantics. For instance, perhaps the best definition of a moon is a body more tidally effected by its putative primary than by the 'the sun'. In a lot of ways this is probably a better definition of 'moon'. And by this definition Luna is a moon. But ultimately who cares what it is called.
