The buoyant force (Fb) on an object is equal to the weight of the fluid it displaces:
Fb = ρf × Vdisp × g
Where:

Given:
Result: Fb = 1176 N (floating)
Given:
Result: Fb = 162 N
Archimedes' Principle states that any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
This principle was discovered by the ancient Greek mathematician and inventor Archimedes of Syracuse in the 3rd century BCE.
The buoyant force (Fb) is the upward force exerted by a fluid on an immersed object. It can be calculated using:
Fb = ρf × Vdisp × g
Where ρf is the fluid density, Vdisp is the volume of displaced fluid, and g is gravitational acceleration.
An object will:
Buoyancy principles are used in many real-world applications:
The calculator will show:
Buoyancy is based on Archimedes' Principle, which states:
"The upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces."
This principle explains why objects float or sink and is fundamental to fluid mechanics.
