A better and more accurate way to get your breasts’ weight is through Archimedes’ principle of liquid displacement. It may take a lot of effort and it may feel awkward. But if you need an accurate measurement, this is the method that you should do.

  • kitchen or bathroom scale
  • large bowl
  • towel
  • tray with a sizable lip
  • pen and paper or calculator

Here are the steps that you should do:

  1. Measure the weight of the tray and write the measurement on your paper.
  2. Put the large bowl inside of the tray. Fill the bowl with water up to the brim. 
  3. Place one of your breasts in the bowl until your chest touches the lip of the bowl lightly.
  4. Take out the bowl. Carry the tray with the displaced water and measure it on the scale.
  5. Subtract the weight of the tray from the tray that contains water.
  6. Multiply your answer by 0.9 because your breast tissues are mostly made of fats. Therefore, it has a different density and weight by volume measurement compared to water.
  7. Repeat steps 2 to 6 for the other breast. You have to measure them separately because they may differ in size, shape, and weight.
