What does volumetric mean?
Volumetric describes something concerned with the volume occupied by an object or with three-dimensional space. In technical and scientific writing, it often contrasts with a merely linear, planar, or surface-based approach: volumetric analysis measures properties throughout a volume, while volumetric imaging reconstructs that space as a three-dimensional representation. The word also appears in engineering, medicine, architecture, graphics, and cloud-computing contexts, where it signals that size and internal space matter, not merely outline or position. As a rare noun, a volumetric is a measurement of volume, with volumetrics used for such measurements collectively. Volumetric is formal and technical rather than everyday, but it is useful when precision about three-dimensional extent is important.
Relating to volume or three-dimensional space; involving the measurement, representation, or analysis of the space occupied by an object.
"The team created a volumetric reconstruction of the damaged structure."
Common in technical fields. In computing and imaging, it often specifically denotes data or representation that describe a full three-dimensional space.
A measurement of the volume occupied by an object or region.
"Clinicians used serial volumetrics to monitor changes in the tumor."
This noun use is specialized and uncommon; the plural volumetrics is more frequent.
The plural is uncommon. In medical and scientific writing, volumetrics may refer collectively to measurements of volume, while a volumetric is an individual measurement.
"Serial volumetrics were used to monitor the lesion over time."
Volumetric puts the focus not merely on an object's shape, but on the space it occupies.

Where does volumetric come from?
The English word was formed in the early 19th century from volume and the combining form -metric. Volume came through Middle French from Latin volumen, meaning a roll, scroll, or volume, and is ultimately related to Latin volvere, “to roll.” The element -metric comes from Greek metron, “measure,” and indicates that the resulting word concerns measurement.

How volumetric is actually used
Volumetric is chiefly formal and technical, common in science, medicine, engineering, architecture, graphics, and data storage. It often emphasizes measurements or representations involving the full three-dimensional extent of something rather than only its surface or outline.
Easily confused with volumetric
Volumetric concerns measurements or three-dimensional space, whereas voluntary means done by choice or without compulsion.
