How to use it
- Enter displaced volume in cubic meters.
- Enter fluid density.
- Calculate ideal buoyant force.
Buoyancy Calculator
Apply Archimedes’ principle to an entered displaced volume and density.

About the Buoyancy Calculator
Estimate the upward force equal to the weight of displaced fluid.
Formula
Buoyant force equals fluid density times gravitational acceleration times displaced volume.
Example
One cubic meter displaced in seawater at 1,025 kg/m³ gives about 10,052 N.
Notes
Stability, hull geometry, loading, motion, reserve buoyancy and structural safety are not evaluated.
