Buoyancy Force Calculator

Buoyancy Force (F_b):

Density of the fluid (ρ):

Acceleration due to gravity (g):

Height difference in the fluid column (Δ h):

How This Is Calculated

$$ F_b = \rho g \Delta h $$ where:

F_b = Buoyancy Force (N)

ρ = Density of the fluid (kg/m³)

g = Acceleration due to gravity (m/s²)

Δ h = Height difference in the fluid column (m)

Assumptions

The fluid is in hydrostatic equalibrium.
The fluid is incompressible.
Density of the fluid remains constant.
Object is fully or partially submerged.
There are no significant viscous forces.
