Physical units in fluid dynamics

Classical Mechanics Level 2

In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid

\[F_D=\frac{1}{2} C_D ρv^2 A\] where

\(F_D\) is the drag force, which is by definition the force component in the direction of the flow velocity,
\(ρ\) is the density of the fluid,
\(v\) is the velocity of the object relative to the fluid,
\(A\) is the reference area, and
\(C_D\) is the drag coefficient.

What units can the quantity \((C_D )^2\) have?
