Buoyancy Force Calculator

Calculates the force acting opposite the direction of gravity that affects all objects submerged in a fluid.


Buoyancy Force Equation Formulas

Buoyant :

The upward force applied by the fluid on the object or the body when an object is put in or submerged in the fluid.

Buoyant Force :

When an object is immersed in a liquid it experiences an upward force known as Buoyant Force.In other words, the buoyancy force on a submerged body is directed in the opposite direction to gravity and is equal in magnitude to

B = Pf × V × g


B - buoyanat force in N

Pf - fluid density in kg/m3

V - displaced body volume of liquid in kg/m3

g = 9.806 m/s2 (standard gravity)
