Cubic millimeters
The cubic millimetre is a unit of volume equal to one thousandth of a cubic centimetre (10⁻⁶ L or 10⁻⁹ m³). It is used in precision engineering, optics, and laboratory science for very small volumes. In clinical haematology, blood cell counts and platelet volumes are sometimes expressed in cubic millimetres per unit volume. Gemstone volumes in jewellery are also occasionally measured in cubic millimetres.
