Peyronie's disease is an uncommon condition, which is, in most cases, related to vascular disease or penile trauma. Symptoms, including penile curvature, shortening, and pain, should initially be treated conservatively with the expectation for improvement or resolution.
1 milliliter (ml) = 1 gram (g). Milliliter (ml) is a unit of Volume used in Metric system. Gram (g) is a unit of Weight used in Metric system. Grams also can be marked as grammes (alternative British English spelling in UK).
Density, however, can be measured in a wide variety of units, like g/cm3 or g/ml. Density = Mass/Volume. The units for density are grams per cubic centimeter ( g/cm3** ) or grams per milliliter ( g/ml ), since a cubic centimeter is equivalent to a milliliter. For example, water has a density of 1 g/ml or 1 g/cm3. What this means is that for every 1 gram of what you have, it takes up 1 milliliter of space (or 1 cubic centimeter). If you were to put 1 milliliter of water in a test tube and find its mass, it would be exactly 1 gram.
