The result in the speed of light, must be a typo in the notes above for inches/sec as the result is metric. It can be done in imperial units, it would require all units to be in imperial, not sure why one would do this as SI is metric and going thru to make sure the units are are on equal footing in metric terms is a fair amount to juggle as is.
