> In reality, a pound operating at a distance of one foot does not exert as much force in Fairbanks as it does in Los Angeles.

A foot-pound of work is the same because it's based on pound-force which is standardized, not a pound-mass.

It's exactly the same as a newton, except if a newton was defined as "force of 1KG mass at standard gravity". The problem is that 1 newton is nowhere near the force of 1KG so it's impossible to intuitively reason about it.
