Density Calculator (ρ = m / V)
Computes density from mass and volume, comparing the outcome with water (1 g/cm³), aluminum (2.7 g/cm³), iron (7.87 g/cm³), and gold (19.32 g/cm³) to assess buoyancy and composition.

STEP-BY-STEP MATHEMATICAL DERIVATION
1Formula: ρ = m / V
2Substitution: ρ = 5 kg / 0.002 m³ = 2,500 kg/m³
3In grams per cubic cm: 2,500 / 1000 = 2.5 g/cm³
4Specific gravity: 2.5 / 1.0 = 2.5
MATHEMATICAL FORMULA & GOVERNING PRINCIPLES
ρ = m / V
Density represents mass per unit volume of a substance, determining whether an object floats or sinks in fluids.
FREQUENTLY ASKED QUESTIONS (FAQ)
Does an object float if its density is lower than water?
Yes. Water at standard temperature has a density of approximately 1,000 kg/m³ (1.0 g/cm³). Any solid with a lower density will float.
