volume
Let an agent handle volume with unit, method, conditions and domain definitions, and avoid confusing volume with capacity or mass.
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 handle volume with unit, method, conditions and domain definitions, and avoid confusing volume with capacity or mass.
The amount of three-dimensional space occupied by a substance or enclosed by a container, measured in cubic metres or litres; domain-specific volumes include stroke volume and lung volumes.
What it is for: Measuring space and amounts of fluids and materials.
It can be measure and calculate it; convert units; correct for temperature and pressure for gases; use it in trade and medicine.
Distinguishing features
Three-dimensional extent
Gas volume depends on temperature and pressure
Capacity of a container differs from contents volume
Loudness volume is a different sense
What it looks like
Numbers with units such as L, mL, m3; graduated containers.
Physical character
SI unit: cubic metre m3 - 1 L = 0.001 m3
US gallon: 3.785 L - imperial gallon 4.546 L
How it is recognised
Units L, mL, m3, gallons
Graduated vessels
Medical volumes such as mean corpuscular volume

What the second pass must settle
- Should medical volumes be separate entries?
- How should reference conditions be recorded?
- The registry entry has merged aliases such as stevedoring; should they be split off?
