High Quality Content by WIKIPEDIA articles! A drag count is a single unit of drag as defined by aerospace engineers.A drag count of 1 is equal to Cd of 0.0001. So if, for example, the steady state drag coefficient is 0.0200 and someone sticks a hand out the window adding 5 drag counts, the new drag coefficient would be: 0.0200 + 0.0005 = 0.0205 or 205 drag counts. Drag count is used as a crude measure for the change in drag coefficient (it is not a direct measure of drag as it is associated with a reference area, it is only valid for use as a relative assessment of change).
