* cc stands for cubic centimeters, a unit of volume.

* mill is a unit of length, often referring to a thousandth of an inch.

To convert between volume and length, you'd need more information about the shape of the object you're measuring.

For example:

* If you have a cube with sides of 1 mill each, the volume would be (1 mill)^3 = 1 cubic mill. You could then convert cubic mills to cubic centimeters using a conversion factor (1 mill = 0.0254 cm).

* If you have a cylinder with a diameter of 1 mill and a height of 1 mill, the volume calculation would be different.

Let me know if you have a specific object or shape in mind, and I can help you with the conversion.
