The diameter and thickness of the penny could be expressed in millimeters = 'mm'. The area of the penny's faces, or even of its edge, could be expressed in square millimeters = 'mm2'. The volume of material in the penny could be expressed in cubic centimeters 'cc' or cubic millimeters 'mm3'. The mass and weight of the penny could both be expressed in grams = 'gm'. The age of the penny since it was minted could be expressed as a large number of seconds = 's'.
The best metric unit to measure the mass of a dime, assuming you mean the coin variety of a dime, would be the gram. The typical weight for a US dime is currently about 2.27grams, though the Canadian dime's weight may differ. If you mean the chocolate bar Dime however, then you should also use grams.
If you have a graduated cylinder you can just fill it with water and note the volume of the water inside the cylinder, and then subtract that from the volume read by the cylinder once the coin has been dropped into the cylinder. You don't need a cork.
Diameter and thickness - millimeters
Weight - grams
try putting it in a graduated cylinder and caluculating it that way. I hope this information helps
To measure a dime it would be best to measure it by millimeters. You could measure it with a ruler.
The volume of a penny might be measured in milliliters.
