How to use this calculator

Enter Fluid density, Gravity, Displaced volume. The calculator applies the stated relationship and keeps full precision until the displayed result is formatted.

The method

Fb = rho x g x V

The calculator evaluates this relationship using standard real-number arithmetic. Intermediate values keep full floating-point precision before the displayed result is formatted.

WORKED EXAMPLE

Fluid density: 1000 kg/m^3, Gravity: 9.80665 m/s^2, Displaced volume: 0.01 m^3

Buoyant force: 98.0665 N
