Archimedes' Principle Calculator
Compute buoyant force F_b = ρ·V·g on a submerged object.
Input Data
Fluid Density Kg Per M3
kg/m³
Volume M3
m³
Gravity Ms2
m/s²
Results
F_b = ρ·V·g.
9.81N
At a glance:Buoyant force = weight of displaced fluid = ρ·V·g. Complements buoyancy and buoyancy-force.
Formula
F_b = ρ·V·g.
$$F_b = \rho_{\text{fluid}} \cdot V \cdot g, \quad \rho_{\text{obj}} < \rho_{\text{fluid}} \Rightarrow \text{float}$$How to Use
- Enter fluid density, displaced volume and g.
- The tool returns the buoyant force.
Case Studies
ρ=1000, V=0.001, g=9.8
F_b = 9.8 N.
FAQ
Floats or sinks?
If F_b ≥ weight, it floats; otherwise it sinks.
