It is estimated that the gross cost of metrication for the U.S. Highway industry would be approximately 200,000,000 dollars. This cost would be spread over a period of years and would be a relatively small fraction of any year's highway expenditures. At the same time, benefits from metrication appear difficult to quantify. Some of these benefits would be the simplification of calculations, scientific and technical coordination with countries presently using the metric system, and a reevaluation of standard values that could take place during metric conversion. Two areas where metrication would have a major impact are computer programs and signs. Conversion of existing computer systems, programs, and procedures would present the following problems: input forms would have to be redesigned; keypunch instructions would have to be rewritten; computer programs would have to be rewritten; saved data would have to be changed; saved files would have to be redesigned; output forms would have to be redesigned; user instructions manuals would have to be rewritten; and increased data guidance would be required during conversion. It is estimated that the cost of converting computer programs might approximate 25% of highway metrication cost. As far as signs are concerned, primary signs showing distance, speed limit, elevation, clearance, and load limit would have to be converted. This could be done, however, only after the public has become familiar with the metric units of measurement. It is suggested that when the change is made, it should be accomplished as quickly as possible. Signing changes are estimated to be about 30% of total costs.
