sci.buoyancy-archimedes Calculator
Calculates the buoyant force on an object as F_b = ρ_fluid × g × V_displaced (Archimedes' principle), and net weight in fluid. A steel sphere of density 7,800 kg/m³ weighs 87% of its in-air weight when submerged in water — the 13% buoyancy correction is significant in precision weighing.
Inputs
Volume M3
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Rho Fluid Kg M3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Rho Object Kg M3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
G M S2
Reference formula or conversion factor shown for context.
Results
