cubic millimetre
Definition
Noun: - A unit of volume in the metric system equal to the volume of a cube with edges each one millimetre in length. It is a very small measure of capacity.
Usage
The term "cubic millimetre" is used in scientific, engineering, and medical contexts to measure extremely small volumes, such as the volume of a drop of water, a grain of sand, or components in microtechnology. - It is typically abbreviated as mm³. - It is a precise measurement for quantifying minuscule amounts of liquid or solid matter.
Examples
Advanced Usage
- Scientific Notation: In technical writing, volumes are often expressed using scientific notation (e.g., 1.5 x 10³ mm³) for clarity with very large or very small numbers of cubic millimetres.
- Conversion Context: The term is frequently used when converting between different metric volume units (e.g., 1,000 cubic millimetres equals 1 cubic centimetre).

- Millilitre (ml): A more common unit of volume; 1 millilitre is equal to 1,000 cubic millimetres.
- Microlitre (µl): A smaller unit; 1 microlitre is equal to 1 cubic millimetre.
Synonyms
- mm³: The standard abbreviation and a direct synonym in technical contexts.
- (No perfect conceptual synonyms exist, as it is a specific unit of measure.)
Related Phrases
- Cubic capacity: A general term for volume measurement, which can be expressed in cubic millimetres for small objects.
- Displacement volume: Often measured in cubic millimetres for small mechanical parts, like engine cylinders in models.
Notes
- The cubic millimetre is part of the International System of Units (SI).
- It is derived from the base unit of length, the metre. One cubic millimetre is (10⁻³ m)³ = 10⁻⁹ cubic metres.
Noun
-
a metric measure of volume or capacity equal to a cube 1 millimeter on each edge
