1. What is a Density Calculator?

Definition: This calculator computes the density of a substance based on its mass and volume.

Purpose: It helps students, engineers, and scientists determine material density, a fundamental property in physics and engineering.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass is divided by volume to obtain the density, which represents how much mass is contained in a given volume.

3. Importance of Density Calculation

Details: Density is crucial for material identification, buoyancy calculations, and determining whether objects will float or sink in fluids.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical density values for common materials?
A: Water is 1000 kg/m³, aluminum is 2700 kg/m³, lead is 11340 kg/m³, and air is about 1.225 kg/m³ at sea level.

Q2: Can I use different units?
A: Yes, but you'll need to convert them to kg and m³ first for this calculator.

Q3: Why is density important in engineering?
A: It affects material selection, structural design, and performance characteristics of products.

Q4: How does temperature affect density?
A: Most materials expand when heated (increasing volume), thus decreasing their density.

Q5: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units of mass/volume.
