=== Aircraft === As noted above, aircraft use their wing area as the reference area when computing <math>c_\mathrm d</math>, while automobiles (and many other objects) use projected frontal area; thus, coefficients are '''not''' directly comparable between these classes of vehicles. In the aerospace industry, the drag coefficient is sometimes expressed in drag counts where 1 [[drag count]] = 0.0001 of a <math>c_\mathrm d</math>.<ref>Basha, W. A. and Ghaly, W.
