Enter the volume and weight of the prostate into the calculator to determine the prostate density. This calculator can also evaluate any of the variables given the others are known.

Prostate Density Formula

The following formula is used to calculate the prostate density.

PD = V / W


  • PD is the prostate density (cm³/g) V is the volume of the prostate (cm³) W is the weight of the prostate (g)

To calculate the prostate density, divide the volume of the prostate by the weight of the prostate. The result is the prostate density in cubic centimeters per gram (cm³/g).

What is a Prostate Density?

Prostate density refers to the ratio of the gland’s volume that is composed of prostate tissue, as opposed to other substances like water or air. It is often measured during medical imaging tests, such as an ultrasound or MRI, to help diagnose conditions like prostate cancer. A higher prostate density can indicate a greater risk of cancer, as tumors can increase the amount of prostate tissue present.

How to Calculate Prostate Density?

The following steps outline how to calculate the Prostate Density (PD).

  1. First, determine the volume of the prostate (V) in cm³.
  2. Next, determine the weight of the prostate (W) in grams.
  3. Next, gather the formula from above = PD = V / W.
  4. Finally, calculate the Prostate Density (PD) in cm³/g.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Volume of the prostate (V) = 10 cm³

Weight of the prostate (W) = 5 g
