Buoyancy Calculator

Find the buoyant force on a submerged object.

Buoyant force (N) 98.1

Formula: F = ρ · V · g (Archimedes)

Step-by-step with your numbers:
1. Values used:
2. Fluid density = 1,000 kg/m³
3. Submerged volume = 0.01
4. Gravity = 9.81 m/s²
5.
6. Buoyant force = Fluid density x Submerged volume x Gravity = 1,000 x 0.01 x 9.81 = 98.1N
Did we solve your problem today?

Archimedes' principle: buoyant force equals the weight of displaced fluid.

The math behind it

F = fluid density × submerged volume × g.

Worked example

0.01 m³ in water → 98.1 N up.

FAQ

Float or sink?

Floats if buoyant force ≥ the object's weight.
