Standard gravity is a defined value, agreed once so that weights compare across the world.

What it means
Real gravity varies from place to place. It is weaker at the equator than at the poles, weaker on a mountain than at sea level, and it shifts with the density of the rock underfoot. A kilogram of flour therefore pushes down slightly harder in Oslo than in Quito. Rather than argue about it, metrologists fixed a single conventional value and defined the kilogram-force against that.
The claim comes from NIST.
