What does micrometrical mean?
“Micrometrical” is an uncommon adjective meaning either extremely minute or, more technically, connected with micrometers and measurements on a micrometer scale. A micrometer is an instrument designed to measure very small distances or dimensions, and its name reflects the Greek roots for “small” and “measure.” The adjective can therefore describe precise adjustments, tolerances, or observations made at extremely fine levels. Its literary use conveys the idea of something so small that it is scarcely perceptible, but it sounds formal and dated compared with common alternatives such as “microscopic,” “minute,” and “miniscule.” In scientific contexts, “micrometric” is often the more usual and transparent choice, while “micrometrical” is especially associated with older technical prose. Understanding the word nevertheless helps distinguish precise instrumental measurement from a broader figurative description of smallness.

"The microscope revealed micrometrical differences in the specimens."
"The technician recorded the micrometrical adjustment before beginning the calibration."
"Only a micrometrical shift in the lens alignment could explain the difference in the images."
This obscure word compresses an entire scientific scale into an adjective: one micrometer is only one-millionth of a meter.

Etymology of micrometrical
The word was formed in the early 19th century from “micrometer,” with the adjective suffix “-al.” “Micrometer” combines the Greek mikros, meaning “small,” with metron, meaning “measure,” and ultimately derives from metron, a measure or measuring instrument. The related term “micrometric” and the prefix “micro-” reflect the same classical roots.
How micrometrical is actually used
The word is uncommon in modern general English. It is chiefly associated with technical or historical writing, while the literary sense emphasizing extreme smallness is now rare.
