Calculate the aerodynamic drag force acting on an object moving through a fluid. This calculator uses the drag equation considering the drag coefficient, fluid density, cross-sectional area, and velocity.
Enter your values below
Sphere ≈ 0.47, car ≈ 0.3, flat plate ≈ 1.2
Air at sea level ≈ 1.225 kg/m³, water ≈ 1000 kg/m³
Projected area perpendicular to flow
Speed of the object relative to the fluid
How this calculator works
Drag force equals one-half times fluid density times velocity squared times drag coefficient times cross-sectional area.
