Sorry, Han. That is pure garbage. Mass is not equal to force
by *any* unitless multiplication factor, exactly or even approximately.
The relationship is f=m.a; Newton's Second Law in most simple
form. You forgot the acceleration!

Wrong again, Han; g is a *variable* not a constant!
The constant 9.80665 m/s2 is a constant invented by humans
(not a natural constant) to lock "gravitational" units to "absolute"
units, unambiguously, by Newton's Second Law.

Still more garbage, Han.
I'm sorry to be so blunt since this conflicts with my high regard
for your great contributions to the advancement of SI.
