If my memory is correct something very similar happened also during the testing of the first 'Star Wars' missiles. The given cost is pure bull. Autocad has a facility where one can convert from metric to imperial dimensions. It would not cost that much to re-design the software to carry out the conversions automatically, including re-selection of standard components. (Except if NASA is still using rotring pens and tracing paper). One issue that would crop up though is some very odd looking sizes. Assume a rod of 1". This will translate to 25.4 mm, no sane Engineer in the rest of the world would specify a size like this, but would go for 25.0 mm. Having studied both systems I can assure you that the Imperial System adds easily 6 months to an Engineer's training.
