Pearl Weight Calculator

This calculator estimates the weight of a pearl based on its diameter and height. It uses an approximate formula to calculate the volume of the pearl, which is then converted to weight assuming a density of 2.7 g/cm³ (typical for pearls).

Calculation Formula

Weight (g) = Volume × Density

Where:
Volume = (4/3) × π × (diameter/2)³
Density = 2.7 g/cm³ (typical for pearls)

Pearl Weight Calculator Calculator Usage Guide

Learn how to use the Pearl Weight Calculator and understand its working principles.

How to Use This Calculator

  1. Enter the diameter of your pearl in millimeters (mm). This is the widest distance across the pearl.
  2. Enter the height of your pearl in millimeters (mm). This is the vertical distance from the highest point to the lowest point.
  3. Click the "Calculate" button to estimate the weight.
  4. The calculator will display the estimated weight in grams (g).

Understanding the Calculation

This calculator uses an approximate formula based on the volume of a sphere to estimate pearl weight. The formula assumes the pearl is spherical in shape, which may not be perfectly accurate for all pearls.

The calculation steps are:

  1. Convert the diameter from millimeters to centimeters (since the density is given in g/cm³).
  2. Calculate the radius by dividing the diameter by 2.
  3. Calculate the volume using the formula for the volume of a sphere: V = (4/3) × π × r³, where r is the radius.
  4. Calculate the weight by multiplying the volume by the density of the pearl material (typically 2.7 g/cm³).

Limitations

This calculator provides an estimate and may not be perfectly accurate for all types of pearls. Factors such as irregular shape, hollow interior, or different composition can affect the actual weight. For precise measurements, it's recommended to use a scale or consult with a gemologist.
