I'll disagree that "the force of gravity" is a good euphemism for weight and vice-versa.
Using them for euphemisms of each other is the main source, IMO, for
the interminable discussion regarding the definition of weight that
have occurred on these discussion lists ad nauseam since I first
started subscribing.
To whit:
F_g = the force of gravity = GMm/r^2 pointing to the center of the earth (in a earth context situation) according to many people.

Weight = mass times free fall acceleration as measured in a relevant reference frame according to many people
