Density Calculator - Mass per Unit Volume

This physics calculator helps you calculate the density of materials using mass and volume. Density is a fundamental property that describes how much mass is contained in a given volume.

Density Definition

• Density: Mass per unit volume of a substance
• Formula: ρ = m/V (Density = mass ÷ volume)
• Symbol: ρ (rho) - Greek letter for density
• Property: Intensive property (independent of amount)

Density Units

• kg/m³: SI unit of density
• g/cm³: Common unit, 1 g/cm³ = 1000 kg/m³
• kg/L: Liquid density unit, 1 kg/L = 1000 kg/m³
• lb/ft³: Imperial unit

Applications

• Material Science: Identifying materials and their properties
• Engineering: Structural design and material selection
• Chemistry: Substance identification and purity testing
• Geology: Rock and mineral identification
• Architecture: Building material selection

Density Categories

• Solids: Generally 1000-20000 kg/m³
• Liquids: Generally 800-2000 kg/m³
• Gases: Generally 0.1-10 kg/m³
• Water: 1000 kg/m³ (reference standard)

Important Notes

• Density is temperature and pressure dependent
• Most materials expand when heated (density decreases)
• Water has maximum density at 4°C
• Density can be used to identify unknown materials
• Buoyancy depends on density differences

Density Relationships

• Buoyancy: Objects float if less dense than fluid
• Pressure: Higher density fluids create more pressure
• Stability: Lower center of mass for higher density
• Transportation: Density affects shipping costs
