1. What is a Density Calculator?

Definition: This calculator determines the density of a substance by dividing its mass by its volume.

Purpose: It helps scientists, engineers, and students quickly calculate material density, a fundamental physical property.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (grams per cubic centimeter)
• \( m \) — Mass (grams)
• \( V \) — Volume (cubic centimeters)

Explanation: Density represents how much mass is contained in a given volume of a substance.

3. Importance of Density Calculation

Details: Density is crucial for material identification, buoyancy calculations, and quality control in manufacturing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common density values?
A: Water is 1 g/cm³, aluminum ~2.7 g/cm³, gold ~19.3 g/cm³, air ~0.0012 g/cm³.

Q2: How do I measure volume accurately?
A: For regular objects use dimensions, for irregular use water displacement method.

Q3: Can I use different units?
A: This calculator uses g/cm³, but you can convert from kg/m³ (divide by 1000) or lb/ft³ (multiply by 0.01601846).

Q4: Why is density important?
A: It determines buoyancy, material purity, and helps identify substances.

Q5: What if my substance is porous?
A: You'll measure bulk density; true density requires excluding pore spaces.
