Buoyancy Calculator: Determine Buoyant Force, Fluid Density, or Volume

Calculate Buoyant Force (Fb)

Density of the fluid (e.g., water = 1000 kg/m³, air = 1.225 kg/m³).
The volume of the object submerged in the fluid (or volume of displaced fluid).
Defaults to Earth's gravity. Can be changed for other celestial bodies.

Discover how to calculate buoyant force, fluid density, or submerged volume with our easy-to-use Buoyancy Calculator. Based on Archimedes' Principle, this tool simplifies complex physics problems, helping you understand why objects float or sink. Ideal for students, engineers, and anyone exploring fluid mechanics.

Formula:

Formula for Buoyant Force:
Fb = ρ × g × V

Where:
Fb = Buoyant Force (in Newtons, N)
ρ = Fluid Density (in kilograms per cubic meter, kg/m3)
g = Acceleration due to Gravity (9.81 m/s2 on Earth)
V = Volume of Displaced Fluid / Submerged Volume of Object (in cubic meters, m3)
