When used in an unqualified sense, it is usual for the term force of gravity to mean the downward force on a body at the surface of Earth.
From Gravity at Earth's Surface, this is approximately $9.8 \ \mathrm N \ \mathrm{kg}^{-1}$
The force of gravity varies across the Earth's surface, and therefore it makes little sense to use it as a standard.
However, the CGPM adopted a standard value of Acceleration Due to Gravity at Earth's Surface of $9.806 \, 65 \, \mathrm N \, \mathrm{kg}^{-1}$ in $1901$.
