 I had a request from a customer wanting convert velocity data taken with units of dB (reference to 1 nm/s) to dB (reference to 1 micro inch/s).

The "hard" way to do this conversion would be:

1. Convert dB (reference to 1 nm/s) to linear units of nm/s)
2. Convert units of nm/s to micro inch/s (aka microns/s). There are 0.03937 micro inch/s per nm/s
3. Convert linear units of micro inch/s to dB (reference to 1 micro inch/s )
