Buoyancy Calculator

Find the buoyant force on a submerged object.

Fluid density (kg/m³)

Submerged volume

Gravity (m/s²)

Calculated Output

Buoyant force (N) 98.1

Formula: F = ρ · V · g (Archimedes)

Step-by-Step Breakdown

1. Values used:

2. Fluid density = 1,000 kg/m³

3. Submerged volume = 0.01

4. Gravity = 9.81 m/s²

6. Buoyant force = Fluid density x Submerged volume x Gravity = 1,000 x 0.01 x 9.81 = 98.1N

Did this calculator solve your problem today?

The math behind it

F = fluid density × submerged volume × g.

0.01 m³ in water → 98.1 N up.

Float or sink?

Floats if buoyant force ≥ the object's weight.
