Understanding Density in Physics
Density is a fundamental property of matter that describes how much mass is contained in a given volume. It's calculated using the formula: Density = Mass / Volume.
Common Densities
Water: 1 g/cm³ (1000 kg/m³)
Air: 0.0012 g/cm³ (1.2 kg/m³)
Gold: 19.3 g/cm³ (19300 kg/m³)
Aluminum: 2.7 g/cm³ (2700 kg/m³)
Common questions
What is the density formula?
Density = Mass / Volume. The standard units are kg/m³, but g/cm³ is also commonly used.
What is the density of water?
The density of water is approximately 1000 kg/m³ or 1 g/cm³ at 4°C (its maximum density).
How do I convert between kg/m³ and g/cm³?
To convert from kg/m³ to g/cm³, divide by 1000. To convert from g/cm³ to kg/m³, multiply by 1000.
