Meters, centimeters, or millimeters. Take your pick.

To measure a diameter, or length, you would use meters, centimeters, or millimeters. To measure the surface area, use square meters, etc. To measure the volume, use cubic meters, etc.

If you have three measurements of length (meters, centimeters, millimeters) and you multiply them together, you will end up with a measure of volume (liters). Of course, if you were to actually do this, you would want to convert all of the lengths into a common unit (convert centimeters and millimeters to meters or convert meters and centimeters to millimeters).
You can measure small lengths in millimeters. Length of a pencil, pen, eraser, length and width of a paper, sheet etc. can be measured in millimeters.
