Archimedes' Principle Formula

Formula

F_b = ρ × V × g

Where:

  • • F_b = buoyant force (N)
  • • ρ = fluid density (kg/m³)
  • • V = volume displaced (m³)
  • • g = gravitational acceleration (m/s²)

The buoyant force equals the weight of the fluid displaced by the object.

Key Points

  • • Object floats if F_b > weight
  • • Object sinks if F_b < weight
  • • Object neutral if F_b = weight
  • • Works for any fluid
  • • Independent of object shape
