When the back pain is too much even when not carrying a backpack, the curious turn to the question “how much do my breasts actually weigh?” It might be awkward to just throw them on a scale (and inaccurate besides). Fortunately, there are a few other methods, though they may seem no less awkward. And remember the weight of heavy breasts can be lifted with a properly fitted bra, that band should be nice and snug, doing all of the lifting so your back doesn't have to!!!
7 Easy Steps detailed as well below.
- Weigh a tray and record
- Fill a bowl to the brim with water
- Submerge your boob completely into the water, and wait for the water to stop overflowing
- Lift your boob out and remove the bowl
The Water Displacement Method
- Weigh the tray with the water that was dispersed from the bowl , record
- Subtract the weight of the tray from the weight of the tray with water
- Multiply this number by 0.9, and this will be your breast weight per boob
- If your back is breaking and your shoulders slouching come in for a FREE fitting, and we will get you fully supported!
- A kitchen scale. A regular bathroom scale won't be as accurate; you need a scale that measures down to fractions of an ounce.
- A bowl large enough to hold one breast.
- A tray to catch the water displaced by your breast. Make sure it's a waterproof tray large enough to hold the bowl, with sides high enough to hold the water without spilling any.
2) You will then need to weigh the empty tray, before it gets filled with water. This way you can subtract that weight from the weight of the tray once it's filled with water and come up with an accurate weight of the water. Go ahead and set the scale to ounces and then set the tray on the scale and record your weight .
3) You will then need to take the tray and set it on a flat surface, fill the bowl that is large enough to fit your breast comfortably, to the brim with water and set it in the middle of the tray. It is important you fill the bowl to the brim so you get and exact measurement of the overflow. If you do not fill the bowl to the brim you will not get the correct amount of overflow, therefor giving you an inaccurate weight. Also, do this without any bra or clothing obstructing the breast and in a place that's private, we don't wanna give away our secrets!! Make the water temperature is suitable for you before you submerge your breast in it.
4) Check that the bowl is in the middle of the tray so you have enough room on all sides for the overflow of water. Bend over and submerge your entire breast in the bowl all the way to your rib cage and chest wall. You want to make sure all of your breast tissue is in the bowl. The water will overflow into the tray, being careful the water stays in the tray and doesn't splash out or overflow, so no double dipping, as this will give you incorrect results.
5) Once your entire breast has been submerged and water is no longer overflowing, gently lift your breast out and take the water filled tray to the scale, being careful not to spill any water or stand in front of a window! Record the weight of the tray filled with water, then subtract the weight of the tray alone from the weight of the tray filled with water. This will give you the weight of the water displaced. (For instance if your water filled tray weighs 30 oz and the tray alone weighs 10 oz, then the weight of the water displaced in 20 oz.) By gosh, I think we've got it!! Speaking of submerging our breasts in water, lets think Summer, and bra sized swimwear!!
Multiply the water weight by 0.9
20 oz X .9 =18 oz
6) Now we have to do a little science, we have to convert the weight of the water to the weight of breast tissue. No worries, this is easy you don't need your thinking cap!!! Since your breast tissue has a different density than water, we have to use a simple conversion to determine the weight of your breast. Simply multiply the weight of the water by 0.9. So in the example above your water weight was 20 ounces, so multiply 20x 0.9 to come up with 18 ounces! Your breast weighs 18 ounces and since 1LB = 16 oz. Your breast weighs 1lb 2 oz. Ta-Dah!!! Since each of our breasts are not equal you can repeat these steps for your other breast, if you would like to know exactly what each breast weighs or just for a really cool party trick!! Now that you know the weight of your breasts, come in and see us for great fitted supportive bras!
If you aren't up for sloshing around in water, just take a look at the charts below they give estimated weights based on bra sizes in US sizing and U.K sizing. This may not be the most accurate weight but it sure is a starting point on estimated breast weight! Just remember, just because you bought your bra in the U.S. does not make it a US size bra, you need to know the manufacturer and if they do their sizing based on the U.S. or U.K. scale.
