- 20.000 kg
Formula: F = ρ × V × g
About Buoyancy Calculator
Buoyancy Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate the buoyant force on a submerged object using Archimedes' principle: F = fluid density × displaced volume × g.
The calculation uses the standard formula F = ρ × V × g and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
Archimedes' principle says the buoyant force equals the weight of the displaced fluid — an object floats when that force matches its own weight.
