millimetristä

Millimetristä is the genitive singular form of millimetri, the SI unit of length equal to one thousandth of a meter. The noun millimetri is borrowed from French millimètre, which in turn derives from milli- (thousandth) and metre. In Finnish, millimetri is declined as a typical -i noun, and millimetristä is used to express possession or to form phrases that denote a millimeter-scale attribute.

The form millimetristä commonly appears in technical and scientific Finnish, especially in contexts involving precision, tolerances, or measurement quality. For example, millimetristä tarkkuutta refers to millimeter-level precision, a phrase frequently found in engineering, manufacturing, and quality control. When expressing quantities after numerals, Finnish typically uses the partitive form millimetriä, as in kolme millimetriä (three millimeters).

In summary, millimetristä is a grammatical variant tied to the unit millimetri and is predominantly used in expressions that describe measurement characteristics at the millimeter scale. The term is standard in technical writing and everyday discussions of precise dimensions, and it reflects the broader use of the metric system in Finnish vocabulary.
