Archimedes Principle is when a body is totally or partly submerged in a fluid it experiences buoyancy (upward force) that is equivalent to the mass of the fluid displaced is calculated using Archimedes Principle = Density*Acceleration Due to Gravity*Velocity. To calculate Archimedes Principle, you need Density (ρ), Acceleration Due to Gravity (g) & Velocity (v). With our tool, you need to enter the respective value for Density, Acceleration Due to Gravity & Velocity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
