centner
Let an agent explain the centner and its regional definitions, convert between centners and other units, interpret agricultural and historical figures, and avoid confusion between metric and historical values.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the centner and its regional definitions, convert between centners and other units, interpret agricultural and historical figures, and avoid confusion between metric and historical values.
A unit of mass used historically and in some countries today, equal to one hundred kilograms in the metric centner used in Germany, Russia and much of Central and Eastern Europe, while the historical zentner and hundredweight varied by region, often around fifty kilograms or one hundred pounds; the centner is used in agriculture and trade for grain, potatoes and livestock, and appears in statistics and historical records.
What it is for: A unit of mass of about one hundred kilograms.
It can be explain regional definitions; convert units; interpret agricultural figures; avoid confusion.
