Density Calculator

Enter mass and volume to calculate density.

Density Calculator

Introduction

A Density Calculator is an easy-to-use online tool that helps you quickly determine the density of an object or substance. Density is a fundamental property in physics, chemistry, engineering, and everyday life. It tells us how much mass is packed into a given volume. For example, gold is denser than aluminum because more mass is contained in the same amount of space.

This tool is especially useful for students, engineers, researchers, and professionals who deal with materials, fluids, or objects where density is an important factor. Instead of manually performing complex calculations, the Density Calculator provides fast and accurate results in seconds.

Formula / Working

The formula for density is: Density (ρ)=Mass (m)Volume (V)\text{Density (ρ)} = \frac{\text{Mass (m)}}{\text{Volume (V)}}Density (ρ)=Volume (V)Mass (m)

Where:

ρ (rho) = Density (kg/m³, g/cm³, lb/ft³, etc.)
m = Mass of the object or substance
V = Volume of the object or substance

👉 Rearranged forms:

Mass (m) = Density (ρ) × Volume (V)
Volume (V) = Mass (m) ÷ Density (ρ)

This means that if you know any two values (mass, volume, or density), you can easily calculate the third using the Density Calculator.

Step-by-Step Usage

Using the Density Calculator is simple:

Enter the Mass of the substance (in kilograms, grams, pounds, or other units).
Enter the Volume of the substance (in liters, cubic meters, cubic centimeters, etc.).
Click Calculate to get the density result instantly.
Optionally, you can switch units to match your preferred measurement system.

Examples

Example 1: Water Density

Mass = 1000 g
Volume = 1000 cm³

ρ=10001000=1 g/cm3ρ = \frac{1000}{1000} = 1 \, g/cm³ρ=10001000=1g/cm3

✅ The calculator will show 1 g/cm³, which matches the standard density of water.

Example 2: Gold Density

Mass = 386 g
Volume = 20 cm³

ρ=38620=19.3 g/cm3ρ = \frac{386}{20} = 19.3 \, g/cm³ρ=20386=19.3g/cm3

✅ The calculator will show 19.3 g/cm³, the known density of gold.

Example 3: Air Density

Mass = 1.2 g
Volume = 1000 cm³

ρ=1.21000=0.0012 g/cm3ρ = \frac{1.2}{1000} = 0.0012 \, g/cm³ρ=10001.2=0.0012g/cm3

✅ The calculator will show 0.0012 g/cm³, which represents the very low density of air.

FAQs

Q1. What is density used for?
Density is used in science, engineering, and industry to identify materials, calculate buoyancy, design products, and analyze fluid behavior.

Q2. Can I calculate density of liquids and gases?
Yes! The Density Calculator works for solids, liquids, and gases as long as you provide the correct mass and volume.

Q3. What are common units of density?

Kilograms per cubic meter (kg/m³)
Grams per cubic centimeter (g/cm³)
Pounds per cubic foot (lb/ft³)

Q4. Why is density important in daily life?
Density explains why some objects float (like wood in water) and others sink (like metal). It’s also essential in cooking, construction, and product design.
