Density and Buoyancy Calculator
Solve density from mass and volume, and calculate buoyant force with float/sink determination.
Density & Buoyancy Calculator
Solve density from mass and volume, and calculate buoyant force with float/sink determination.
Density (ρ = m / V)
Fill any two fields to solve for the third.
Density Results
Density (ρ): 2,000 kg/m³
Mass (m): 10 kg
Volume (V): 0.005 m³
Buoyancy (F_b = ρ_fluid · V · g)
Calculate the buoyant force and determine if an object floats or sinks.
Buoyancy Results
Buoyant Force: 49.03325 N
F_b = ρ_fluid × V × g = 1000 × 0.005 × 9.80665
Object floats (ρ_object ≤ ρ_fluid)
Density and Buoyancy Calculator
This free calculator solves for density, mass, or volume given the other two values, and calculates buoyant force using Archimedes’ principle to determine whether an object floats or sinks. No sign-up required.
- Density: solve for ρ, m, or V given any two
- Buoyant force: F_b = ρ_fluid × V × g
- Float or sink determination
- Common fluid density presets (water, seawater, mercury)
