Used by students, teachers, engineers, chemists, and researchers worldwide. Master density calculations with professional accuracy and educational support!
The SI unit for density is kilograms per cubic meter (kg/m³). However, in scientific contexts, grams per cubic centimeter (g/cm³) is commonly used since 1 g/cm³ = 1000 kg/m³. Water has a density of approximately 1000 kg/m³ or 1 g/cm³.
Density decreases with increasing temperature for most materials due to thermal expansion. For precise calculations, especially with gases and liquids, temperature must be specified. Our calculator includes temperature-adjusted densities for common materials.
Common densities: Water: 1 g/cm³, Iron: 7.87 g/cm³, Aluminum: 2.70 g/cm³, Gold: 19.32 g/cm³, Air: 0.0012 g/cm³, Ice: 0.92 g/cm³. Our preset database includes these and many more.
For irregular objects, use the water displacement method to find volume. Measure mass, then submerge in water to measure displaced volume. Density = Mass ÷ Volume. Our calculator works with any volume measurement method.
