How It Works

Enter the three dimensions (Length, Width, Height) measured via ultrasound. The calculator applies the standard ellipsoid formula (L × W × H × π/6).

Worked Examples

Dimensions 4.0 × 3.5 × 3.0

Formula:4.0 × 3.5 × 3.0 × 0.523= Multiply
Volume:21.966= 22.0 cc

Tips & Best Practices

  • Standard formula constant is π/6 ≈ 0.523.
  • Normal prostate volume is typically considered < 30 cc (or mL).

Frequently Asked Questions
