A millimeter is a unit of length, not a unit of volume or capacity. Perhaps you mean a cubic millimeter.
If you mean capacity in the sense of volume, the main unit would of course be the cubic meter; other units used include cubic decimeters (equal to liters), cubic centimeters, cubic millimeters.
The cc (cubic centimetre). The litre is the unit of capacity.
There is no SI base unit for capacity. In order to express capacity using SI units, you must resort to a derived unit, such as m³ or cm³ (cubic meters or cubic centimeters). In the metric system, the measurement of Liters (or Litres) may be used, but this is not an SI unit. One liter is equal to 1 dm³ (one cubic decimeter), which is a derived SI unit.
cubic feet or cubic inches
In decreasing order: cubic decimeter = liter cubic centimeter = milliliter cubic millimeter
A foot is a unit of length. A cubic inch is a unit of capacity. The two units are therefore incompatible.
A centimetre is a unit of distance. A cubic millimetre is a unit of capacity. The two units are therefore incompatible.
