Plot Axis Unit Conversions

Hello everyone, I am working on a notebook involving a flutter analysis of a flat plate in a wind tunnel. All of the equations involve metric units, but most of the physical measurements of size I have are in inches. In order to maintain a consistent system of units, I would like to plot the axis units in metric and English units. Specifically, I have a plot for the critical flutter speed in units of m/s versus the chord length in meters, and I want to overlay an x-axis, possibly on the top, that will display the equivalent length in inches (i.e, xinches=x*10000/254) without messing up the graph. At the very least, I would like to display it in centimeters instead of meters for better clarity. I do NOT want to recalculate the function using inches - just display the conversion. It would be nice if I could display it in both inches and centimeters at the same time. This is an absolute breeze to do in another system, but I haven't been able to find anything specifically dealing with scaling of axes for Mathematica. Anyone have any ideas? Thanks very kindly!
