Formula
The Buoyancy Force Calculator uses the formula:
Buoyant force = Fluid density × Gravity × Displaced volume
Worked example
For example, with fluid density of 1,000 kg/m³, gravity of 9.81 m/s² and displaced volume of 0.01 m³, the buoyant force is 98.1000.
| Fluid density | 1,000 kg/m³ |
|---|---|
| Gravity | 9.81 m/s² |
| Displaced volume | 0.01 m³ |
| Buoyant force | 98.1000 |

Key terms explained
- Density
- Mass per unit volume, calculated as mass ÷ volume.
- Force
- A push or pull on an object, equal to mass × acceleration (Newton's second law).
- Volume
- The amount of three-dimensional space an object occupies, measured in cubic units.
Frequently asked questions
Multiply fluid density, gravity and displaced volume: F = ρgV. An object displacing 0.01 m³ of water feels about 98 N upward.
It states the buoyant force equals the weight of the fluid an object displaces.
They float when the buoyant force equals their weight, which happens if they are less dense than the fluid overall.
Yes. Denser fluids like seawater give more buoyancy, so objects float higher than in fresh water.
Enter the fluid density. Enter the gravity. Enter the displaced volume. Read off your buoyant force — the calculator updates automatically, with no button to press.
