To add a little perspective ... didn't NASA scientists make a billion dollar mistake for a Mars project by neglecting to convert units (or is that story apocryphal)?
It's not apocryphal, but my understanding is that the problem was a clash between a system which output data in one set of units and another expecting data in the other set. It's a quibble, but it was really a systems engineering oversight--both systems worked as advertised, but apparently they weren't tested against each other.
