Drag coefficient - SCx to Cd

[CarlT]

Can anyone help?

I have the drag coefficient measurement of a vehicle in SCx and need to convert it to Cd. A quick Google search has been fruitless. Can anyone tell me how to convert one to the other?

Thanks

AFAIK Cx and Cd are interchangeable terms, but I've no idea what the S stands for unless it's a variant on Area (Surface Area perhaps ? )

in that case, you need to divide the SCx figure by the area presented by the object to get the Cx or Cd figure.
