ρ = m / V | m = ρ × V | V = m / ρρDensity (Greek letter rho)mMassVVolumeDensity is a fundamental physical property that describes how much mass is packed into a given volume. It determines whether objects float or sink (objects less dense than water float), and is crucial in materials science, chemistry, and engineering.
Density is one of the most fundamental physical properties of matter. It determines whether objects float or sink, how materials behave under pressure, and how substances can be identified. From engineering design to chemistry experiments to everyday curiosity about why some things float, density calculations are essential across many fields.
Select two known quantities (any combination of density, mass, and volume), enter their values with appropriate units, and the calculator solves for the third. Results are provided in multiple unit systems for convenience.
This calculator supports a comprehensive range of units for mass (grams, kilograms, pounds), volume (cm³, mL, liters, m³), and density (g/cm³, kg/m³), making it suitable for both scientific and everyday applications.
A common mistake is confusing mass and weight. Mass is the amount of matter (measured in kg or g); weight is the gravitational force on that mass (measured in Newtons). For density calculations, always use mass, not weight. Also, ensure volume and mass units are compatible (both metric or both imperial).
Calculate voltage, current, resistance, and power using Ohm's Law. Essential for electronics and electrical engineering.
Calculate speed, distance, or time using the fundamental physics relationship. Supports multiple units including km/h, mph, and m/s.
