About This Tool
Our free density calculator uses the fundamental formula ρ = m/V (density equals mass divided by volume) to solve problems involving material density. Whether you need to calculate density, mass, or volume, this calculator handles it all. It also calculates specific gravity (relative to water) for easy comparison with known materials. Perfect for students, engineers, scientists, and anyone working with materials or fluids. The calculator supports multiple units including kilograms, grams, pounds, ounces for mass; cubic meters, liters, milliliters, cubic feet, cubic inches for volume; and kg/m³, g/cm³, g/mL, lb/ft³ for density. All calculations happen instantly in your browser with complete privacy.
Frequently Asked Questions
What is the density formula?
The density formula is ρ = m/V, where ρ is density, m is mass, and V is volume. Density measures how much mass is contained in a given volume.
What units does this calculator support?
Our density calculator supports kilograms, grams, pounds, and ounces for mass; cubic meters, liters, milliliters, cubic feet, and cubic inches for volume; and kg/m³, g/cm³, g/mL, and lb/ft³ for density.
What is specific gravity?
Specific gravity is the ratio of a substance's density to the density of water at 4°C (1000 kg/m³). It's a dimensionless quantity that indicates how dense a substance is compared to water.
Can I calculate mass or volume from density?
Yes, you can solve for any variable. If you know density and volume, you can calculate mass. If you know density and mass, you can calculate volume.
