Archimedes' Law - Buoyant Force Calculator

Calculate the buoyant force acting on a submerged or floating body using Archimedes' principle. The buoyant force equals the weight of the liquid displaced by the body.

Archimedes' Law

Archimedes' principle states that the buoyant force acting on a submerged or floating body equals the gravitational force on the liquid displaced by the body.

Formula

FB = V × ρ × g

Where:

  • FB = buoyant force (N)
  • V = volume of body below surface (m³)
  • ρ = density of fluid (kg/m³)
  • g = acceleration of gravity (9.81 m/s²)
