Buoyancy Mass Calculator
🛠️ What Is a Buoyancy Mass Calculator?
A Buoyancy Mass Calculator is an online physics tool that helps you determine the mass displaced by an objectsubmerged in a liquid or gas. It uses the equation:
Buoyant Force (Fb) = ρ × V × g
Where:
ρ = Density of fluid (kg/m³)
V = Volume of displaced fluid (m³)
g = Acceleration due to gravity (9.81 m/s²)
Once the buoyant force is known, the equivalent displaced mass can be easily calculated.

🙋 Frequently Asked Questions (FAQs)
Q1. What is buoyant mass?
A: Buoyant mass is the mass of fluid displaced by an object. It corresponds to the weight of fluid the object pushes away while submerged.
Q2. Does this calculator work for gases too?
A: Yes! Just input the density of the gas (e.g., air) instead of a liquid like water.
Q3. Can I use this for irregularly shaped objects?
A: Yes, if you know the volume displaced. You can find this via submersion or 3D scanning.
Q4. What units are supported?
A: You can input volume in m³, cm³, or liters and density in kg/m³ or g/cm³. The result adapts accordingly.
Q5. Is this based on Archimedes’ Principle?
A: 100%. The formula used is derived directly from Archimedes’ Principle for buoyant force.
