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, scientists, and engineers determine material properties for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Density is calculated by dividing mass by volume. The result depends on the units used for mass and volume.

3. Importance of Density Calculation

Details: Density is a fundamental material property used in material identification, buoyancy calculations, and quality control.

4. Using the Calculator

Tips: Enter the mass in grams and volume in cubic centimeters. All values must be > 0. The result will be in g/cm³ (equivalent to g/mL).

5. Frequently Asked Questions (FAQ)

Q1: What are common density units?
A: The most common are g/cm³, g/mL (1 g/mL = 1 g/cm³), and kg/m³ (1000 kg/m³ = 1 g/cm³).

Q2: How do I convert between density units?
A: 1 g/cm³ = 1 g/mL = 1000 kg/m³. Multiply by 1000 to convert g/cm³ to kg/m³.

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

Q4: Why does density matter in construction?
A: Density affects material strength, weight, and suitability for different applications.

Q5: How does temperature affect density?
A: Most materials expand when heated (increasing volume), thus decreasing density.
