I assume you are asking how grams relates to pounds. To do the convervions, multiple the grams by 0.0022 to find the weight in pounds. 650 x 0.0022 = 1.433 pounds.That does not sound like alot but it is when you are carrying it around your neck all day.If you want to know how that relates to your breasts, we would need to know your breast size. height, weight and probably do an exam. It is very tough to give an exact size that would result from removal of a specific weight of breast tissue. It is difficult to go into surgery with the thought that "I have to remove 650 grams" rather than "I need to reduce the breast size to relieve symptoms and have an attractive breast with sensation when finished".Unfortunately, insurance companies seem to be getting hung up on a specific amount of weight that needs to be removed in order for them to consider the procedure "medically necessary". That is why we jump through the hoops of trying to determine the weight.I hope I answered your question
When I talk to patients about reductions. I rarely talk about absolute gram amounts. They mainly care about their breast weight being taken off of the bras and their backs. There have never been any reports relating absolute reduction weights to resolution in symptoms. Only studies to show that reductions aid in relief of back neck and shoulder discomfort. To simply answer your question, 650 grams is a mass (not a volume) of about 1 pound 7 ounces. Because the breast is composed of a variable amount of fat and gland and its density can be so varied, it is impossible to say exactly the volume. If you breast were exactly the density of water ( normal mix of gland and fat) that would equate to the volume of just shy of two 12 ounce coke cans .
