1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's a fundamental concept in physics and engineering that helps characterize materials and predict their behavior.

2. How Does the Calculator Work?

The calculator uses the density equation:

Where:

• \( \rho \) — Density (mass/volume)
• \( m \) — Mass (mass units)
• \( V \) — Volume (cubic length units)

Explanation: The equation shows the direct relationship between mass and volume in determining a substance's density.

3. Importance of Density Calculation

Details: Density calculations are essential for material identification, buoyancy predictions, quality control in manufacturing, and many scientific applications.

4. Using the Calculator

Tips: Enter mass in any consistent mass units and volume in cubic length units. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for density?
A: Common units include kg/m³ (SI), g/cm³, lb/ft³, and specific gravity (dimensionless).

Q2: How does temperature affect density?
A: Density typically decreases with increasing temperature due to thermal expansion (except for water between 0-4°C).

Q3: What's the density of water?
A: Pure water at 4°C has a density of 1 g/cm³ or 1000 kg/m³.

Q4: How is density used in real-world applications?
A: Applications include shipbuilding (buoyancy), material selection, purity testing, and geological surveys.

Q5: What is specific gravity?
A: Specific gravity is the ratio of a substance's density to the density of water at 4°C (dimensionless).
