Enter mass in kilograms and volume in liters. Convert units before entry if needed; the result is mass divided by volume, not a material lookup.

What This Calculator Does
The Density Calculator calculates physical density from mass in kilograms and volume in liters. It reports standard SI density in kilograms per cubic meter (kg/m³) and laboratory density in grams per cubic centimeter (g/cm³).
How It Works
Density is defined as mass divided by volume (ρ = m / V). One liter equals 0.001 cubic meters, so dividing mass in kg by volume in liters and multiplying by 1,000 gives kg/m³. Dividing kg/m³ by 1,000 gives equivalent g/cm³.
Example
A sample with mass 5 kg occupying 2 liters of volume has a density of 2,500 kg/m³ (or 2.50 g/cm³), which is roughly comparable to standard glass or aluminum.
Formula
ρ = Mass / Volume1 kg/L = 1,000 kg/m³ = 1 g/cm³Reading the Results
Kilograms per cubic meter
The standard International System of Units (SI) measure for volumetric mass density.
Grams per cubic centimeter
Commonly used in chemistry and materials science; water at 4°C has a density of 1.0 g/cm³.
Frequently Asked Questions
What is the density of pure water?
Pure liquid water at 4°C has a density of 1,000 kg/m³ (1.0 g/cm³ or 1.0 kg/L), serving as the standard reference for specific gravity.
Will an object float or sink in water?
If an object average density is less than 1.0 g/cm³ (1,000 kg/m³), it will float in water. If its density is greater, it will sink.
How does temperature affect material density?
Most materials expand when heated, increasing volume and slightly decreasing density. Gases are especially sensitive to temperature and pressure changes.
