Buoyancy Calculator

Calculate buoyant force, displaced volume, or fluid density using Archimedes' principle

Fluid Density (kg/m³) Gravity (m/s²)

Buoyant Force (N) Displaced Volume (m³)

Result

F_b = 98.07 N

F_b = ρ × g × V

Archimedes' Principle: F_b = ρ × g × V · ρ = F_b ÷ (g × V) · V = F_b ÷ (ρ × g)

About: Archimedes' principle states that the buoyant force on a submerged object equals the weight of the fluid displaced: F_b = ρ × g × V. This is why ships float, balloons rise, and submarines can dive and surface.
