Can I use this calculator to find the density of an unknown object?

Yes, by entering the object's mass and volume, the tool computes its density and compares it to the selected fluid to predict whether it will float or sink.

What fluid types are available in the dropdown menu?

The calculator offers common fluids such as water, sea water, alcohol (ethanol and methanol), fuel oil, heating oil, sulfuric acid (95%), and vehicle gasoline, plus a custom option for entering a specific density value.

Does the tool account for partial submersion or only fully submerged objects?

The calculator is designed for objects that are completely submerged; partial submersion requires adjusting the displaced volume manually.

Is the gravitational acceleration value fixed, or can I change it?

The default is standard gravity, but users can input a different value for the acceleration due to gravity if their scenario requires it.

About this tool

What Archimedes' Principle Calculator does

The Archimedes' Principle Calculator on Omni Calculator computes the buoyant force and related properties of an object submerged in a fluid. Users input known variables such as object volume, fluid density, and gravitational acceleration to determine true and apparent mass and weight, fluid displacement, and buoyancy force. The tool is designed to clarify why objects float or sink and can also be used to calculate object density. It presents the physics concept with plain-language explanations and real-world context alongside the computation interface.
