Just read your article. It is good to know the history of NIST in this area.

I am also aware of a long-standing effort at the National Institute of Building Sciences NIBS for conversion to SI Metric. NIBS has a group called the Construction Metrication Council (www.nibs.org/cmchome.html). NIBS is a nonprofit organization that with the following charge:

The National Institute of Building Sciences (NIBS) was authorized by the U.S. Congress in the Housing and Community Development Act of 1974, Public Law 93-383. In establishing NIBS, Congress recognized the need for an organization that could serve as an interface between government and the private sector. The Institute's public interest mission is to: improve the building regulatory environment; facilitate the introduction of new and existing products and technology into the building process; and disseminate nationally recognized technical and regulatory information.

My question is: How are NIBS and NIST working together to create national standards for metric units? Will there be a document that consolidates all the rules for conversion, rounding, and assignment of correct corresponding units between conventional I-P units and SI Metric Units?
