The critical problems that must be faced during the transition from the conventional inch/pound system to Systeme International des Unites (SI) are highlighted. Problems encountered by the British aerospace industry during their transition from imperial measure to SI are assessed. The problems that face United States industry are defined, and ways for alleviating them are suggested in a series of recommendations that constitute a plan for transition to metric at the company level.
