1. What is the Density Formula?

Definition: Density is defined as mass per unit volume of a substance.

Purpose: This calculator helps determine the density of materials, which is crucial in physics, engineering, and material science.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³ or g/cm³)
• \( m \) — Mass (kg or g)
• \( V \) — Volume (m³ or cm³)

Explanation: The mass is divided by volume to obtain the density of the material.

3. Importance of Density Calculation

Details: Density is fundamental for material identification, buoyancy calculations, and determining material purity or composition.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common density units?
A: Common units include kg/m³ (SI units) and g/cm³. 1 g/cm³ = 1000 kg/m³.

Q2: What's the density of water?
A: Pure water at 4°C has a density of 1000 kg/m³ or 1 g/cm³.

Q3: How does temperature affect density?
A: Most materials expand when heated (lower density) and contract when cooled (higher density).

Q4: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units.

Q5: Can I use different units?
A: Yes, but ensure consistent units (e.g., g with cm³, kg with m³) for accurate results.
