the Kilogram is defined as artifact prototype rather than the meter which is defined according to speed of light however, I have a definition that may be both simple and good:
"the Kilogram is a mass of a ball when it rotates in one meter radius it would be pulled by one newton force towards its center of rotation." for the force just a scale will be valid to measure it everywhere.
this happens everywhere in space and any ball of any material will subject to the same centripetal force, considering that rotating of objects around a center is a phenomenon in both atomic physics and astronomy.

...definition ... the Kilogram is a mass of a ball when it rotates in one meter radius it would be pulled by one newton force towards its center of rotation.
The centrifugal force (https://en.wikipedia.org/wiki/Centrifugal_force) will depend on how fast your olympic hammer is spinning, you haven't specified that speed in your definition.

" The Kilogram is a mass of a ball spinning in one meter radius circle with frequency 1/2π Hz subject to one newton centripetal force"

" The Kilogram is a mass of a ball spinning in one meter radius circle with frequency 1/2π Hz subject to one newton centripetal force"
...and the definition of a Newton is?
-
the newton may have alternative definition , which is the force to make displacement in meters in a spring with particular metal and particular dimensions .

Problem then is that you have returned to a manufactured material standard and a force dependent on g, which varies from place to place. The aim of standards committees is to replace material standards with absolutely reproducible natural phenomena.
