magnitude
Let an agent explain magnitude as a general property and its measurement, describe specialised magnitude scales such as those for earthquakes and stars, support comparison and classification of values, and clarify usage.
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 magnitude as a general property and its measurement, describe specialised magnitude scales such as those for earthquakes and stars, support comparison and classification of values, and clarify usage.
The size, extent or amount of something as a measurable property, whether the length or mass of an object, the size of a family, file or document, a font size, or the scale of an event such as an earthquake or star brightness, including values judged abnormally high or low against a reference; magnitude is expressed in units or on scales, compared across cases, and is a general concept in mathematics, science and everyday description.
What it is for: Size or amount as a property.
It can be explain the concept; describe specialised scales; support comparison; clarify usage.

What it looks like
Not physical; a measured or judged quantity.
How it is recognised
