A small bucket or cooking pot should also work if you don’t have a bowl that you can easily fit one of your breasts into.

Use a scale that can measure in ounces and fractions of ounces. This will help you get a more accurate weight than if you used larger units of measurement, like pounds. Write down the weight of the tray so that you don’t forget it!

For your own comfort, you may wish to use warm water.

Some of the water should spill over the sides of the bowl into the tray. Do this without a bra on so that the bra won’t absorb water and interfere with the measurement.

Be careful not to spill any of the water from the tray when you move it onto the scale. For example, if you get a result of 25. 3 ounces (720 g) and your tray weighed 3. 2 ounces (91 g), subtract 3. 2 ounces (91 g) from 25. 3 ounces (720 g). The resulting weight of the water is 22. 1 ounces (630 g).

For example, if the displaced water weighs 35 ounces (990 g), multiply that by 0. 9 to get 31. 5 ounces (890 g). That is the approximate weight of your breast. To convert ounces to pounds, divide the weight in ounces by 16. For the previous example, divide by 31. 5 ounces (890 g) by 16, which is equal to 1. 97 pounds (0. 89 kg).

To get the most accurate possible results, try weighing each beast 2-3 times to make sure you get a consistent measurement each time.

For example, if the measurement you get is 30 inches (76 cm), add 4 to get your band size of 34.

For example, if you get a measurement of 35. 6 inches (90 cm), round it up to 36 inches (91 cm). It’s best to do this without a bra on so that you get an accurate measurement.

If the difference is 0 inches (0 cm), you are an AA cup. If the difference is 1 inch (2. 5 cm), you are an A cup. If the difference is 2 inches (5. 1 cm), you are a B cup. If the difference is 3 inches (7. 6 cm), you are a C cup. If the difference is 4 inches (10 cm), you are a D cup. If the difference is 5 inches (13 cm), you are a DD or E cup. If the difference is 6 inches (15 cm), you are a DDD or F cup. If the difference is 7 inches (18 cm), you are a G cup. If the difference is 8 inches (20 cm), you are an H cup. If the difference is 9 inches (23 cm), you are an I cup. If the difference is 10 inches (25 cm), you are a J cup. Alternatively, you can find your cup size by filling in your measurement info using an online bra size questionnaire. Use search terms like “bra fit quiz. ”

If you’d rather not do all the measurements yourself, you can also go to a lingerie store and get a professional fitting.

The accuracy of the method will depend on a variety of factors, including the size and shape of your breasts and body and how easily you can fit your whole breast into a container of water. Your doctor might also recommend other methods, such as taking a cast of your breast and estimating the volume and weight based on that.
