Density Calculator — Frequently Asked Questions
Q1 What is the formula for density? ▾
Density = Mass / Volume (ρ = m / V). Standard SI units are kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
Q2 What is the density of pure water? ▾
Pure liquid water has a density of approximately 1.000 g/cm³ (1,000 kg/m³ or 8.34 lbs/gal) at 4°C.
Q3 What is specific gravity and how does it relate to density? ▾
Specific gravity is a dimensionless ratio comparing the density of a substance to the density of water. A substance with specific gravity > 1 sinks in water, while < 1 floats.
Q4 How does temperature affect material density? ▾
Most substances expand as temperature rises, increasing volume and decreasing density. Water is a notable exception between 0°C and 4°C, where it reaches peak density.
