Density Calculator

Calculate density for various materials including air, water, gases, pixels, PSA and more. Support for different units, temperatures, pressures and conditions.

Density Units

Material Density Calculator

Calculate density using mass and volume, or select common materials.

Material Type

Mass

Volume

m³

Formula: Density = Mass ÷ Volume
Select a material to use its standard density value.

1000.0000 kg/m³

Material Density

Calculation:
Density = 1000 kg ÷ 1 m³
Density = 1000.00 kg/m³

Common Material Densities (kg/m³):

Water: 1000

Air: 1.225

Iron: 7870

Gold: 19300

Density Calculation Guide

Density Formulas

Material Density: ρ = m ÷ V
Air Density (Ideal Gas): ρ = P ÷ (R × T)
Gas Density: ρ = (P × M) ÷ (R × T)
Pixel Density: PPI = √(w² + h²) ÷ d
PSA Density: PSAD = PSA ÷ Volume

Common Density Values

• Water: 1000 kg/m³ (4°C)
• Air: 1.225 kg/m³ (15°C, sea level)
• Iron: 7870 kg/m³
• Gold: 19,300 kg/m³
• Wood: 700 kg/m³ (oak)
• Helium: 0.179 kg/m³ (STP)

Real-World Applications

• Engineering: Material selection, buoyancy calculations
• Meteorology: Weather forecasting, air density effects
• Chemistry: Gas behavior, reaction conditions
• Technology: Display quality assessment, pixel density
• Medicine: Prostate health assessment, PSA monitoring

Factors Affecting Density

• Temperature: Most substances expand when heated
• Pressure: Gases compress under pressure
• Composition: Impurities and mixtures
• Phase: Solid, liquid, gas states
• Altitude: Air density decreases with height
