Calculation Formula

Mass = Volume × Density

Where:
Mass is the mass of the planet in kilograms
Volume is the volume of the planet in cubic kilometers
Density is the density of the planet in grams per cubic centimeter

Planet Mass Calculator Usage Guide

Learn how to use the Planet Mass Calculator calculator and its working principles

How to Use This Calculator

  1. Enter the volume of the planet in cubic kilometers (km³)
  2. Enter the density of the planet in grams per cubic centimeter (g/cm³)
  3. Click the "Calculate" button to compute the planet's mass
  4. The result will be displayed in kilograms (kg)

Understanding the Formula

The calculator uses the simple formula:
Mass = Volume × Density

This formula works because mass is directly proportional to both volume and density. For example, if you know that Earth has a volume of approximately 1.083 trillion km³ and an average density of about 5.51 g/cm³, you can calculate Earth's mass as follows:

Mass = 1,083,000,000,000 km³ × (5.51 g/cm³ × 1,000,000 kg/km³) ≈ 5.972 × 10^24 kg

This matches Earth's actual mass, demonstrating that the calculator can be used to estimate planetary masses when volume and density are known.
