🧪 Common Densities

Water: 1 g/cm³

Aluminum: 2.70 g/cm³

Iron: 7.87 g/cm³

Gold: 19.3 g/cm³

📊 Density Facts

Higher density: Sinks in liquid

Lower density: Floats in liquid

Buoyancy: Based on density difference

Material selection: Density affects weight

How to Use the Density Calculator

Enter a density value, select the current unit (kg/m³, g/cm³, lb/ft³, etc.), choose your target unit, and get instant conversion. Used in chemistry, materials science, and engineering.

Formula

All densities convert through kg/m³ (base SI unit). value_in_kg_m3 = input × from_factor; result = value_in_kg_m3 ÷ to_factor.

History & Interesting Facts

💡 Did You Know?

Water has a density of 1 g/cm³ (or 1,000 kg/m³), making it a reference standard. Ice floats because it is less dense than liquid water.

Origin & History

Density is mass per unit volume. Archimedes famously used density to expose counterfeit gold, discovering the principle by displacement.

Frequently Asked Questions

What is density?

Density is the mass of a substance per unit volume. Formula: Density = Mass ÷ Volume. Units are kg/m³ or g/cm³.

Why does ice float on water?

Ice has a lower density (~0.92 g/cm³) than liquid water (1.0 g/cm³), so it floats. This is unusual; most solids sink in their own liquid.

What is the density of aluminum?

Aluminum has a density of 2.70 g/cm³ or 2,700 kg/m³. It is much less dense than iron (7.87 g/cm³).
