any mass is big to be concerned if you're thinking it might be cancer. but my doctor said that you don't have to really worry unless you notice it growing. if it is pretty much a circle shape, you don't usually have to worry. also, see if it moves when you push it around. if it does, that's ok. if it doesn't, that might be a problem. if you're really worried, see if you can get it removed. cryogenic 'freezing' or cauterization 'burning' are the most common ways, if it's like a mole. if it's too big, they will have to remove it surgically, but can still do it in the office.

An inch is equivalent to 2.54 centimeters exactly as a conversion so 2 cm is about .79 inches or just over 3/4 of an inch...that is somewhere between the diameter of a penny and the diameter of a nickel
1 centimeter = 10 millimetersso20 millimeters = (20 / 10) = 2 centimeters
(1/2 centimeter)=0.196850394 inches
The definition of density is mass/volume. You have a volume (I assume) of 20cm^3, or 20 cubic centimeters, and a mass of 40 grams. You answer would therefore be 2 grams/cubic centimeter, which you can convert into your favorite units as you please. SI units would be kg/cm^3.
It is a linear length and as a ruler it is not round.
Centimeter is 1/100 of a meter. One tenth of centimeter is 1/1000 of a meter ... or it is milimeter.
