Buoyancy Calculator

Calculate buoyant force using Archimedes' principle.

Buoyancy Calculator: Archimedes' Principle

Calculate the buoyant force acting on an object. Determine if it will float or sink based on density and volume.

Why Things Float

Archimedes' principle states that the upward buoyant force on a submerged object is equal to the weight of the fluid that the object displaces.

Formula

Fb = ρ * V * g
  • ρ = Fluid Density
  • V = Displaced Volume
  • g = Acceleration due to gravity
