What to enter
| Input | Meaning and units |
|---|---|
| Fluid density (kg/m³) | Enter fluid density in kg/m³; use the same basis as the other measurements. |
| Displaced volume (m³) | Net volume in cubic metres. Convert cubic units before entering the value; outside dimensions of hollow objects are not net material volume. |
| Gravity (m/s²) | Enter gravity in m/s²; use the same basis as the other measurements. |
Understanding your result
Read Buoyant force (N) in the units and model stated on this page. The formula force=rho*volume*g defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
