The most common term for precision in technical, scientific, and engineering contexts. Refers to the degree of exactness of a measurement or instrument.
This machine processes parts with high precision.
We need to improve the precision of the measurement.
Emphasizes the meticulousness and fineness of detail, often used for instruments or workmanship. More about the quality of being precise rather than a numerical measure.
