Information on the SI within this reference is primarily based on three NIST publications, which are available in electronic (acrobat pdf) format. (If you do not have this software, you may wish to obtain it free from Adobe.)
Note: The BIPM SI Brochure (9th Edition) was published on May 20, 2019. The corresponding editions of NIST SP 330:2019 is now available. An updated edition of SP 811 will be published soon that reflects the changes incorporated in the BIPM SI Brochure (9th Edition). Electronic copies of SP 330:2019 and SP 811:2008 are available online from the Bibliography.

NIST Special Publication 330, The International System of Units (SI), 2019 Edition, David B. Newell and Eite Tiesinga, Editors
This publication, abbreviated SP 330, is the U.S. version of the English language text of the 8th edition of the brochure Le Système International d'Unites (SI). The 8th edition of the brochure, which is the current definitive reference on the SI, was published in the French language in 2006 by the International Bureau of Weights and Measures (BIPM, Bureau International des Poids et Mesures). Except for very minor differences, SP 330 is identical to the English-language text that follows the official French language text in the two BIPM publications. The BIPM SI Brochure, and thus SP 330, contains Resolutions and Recommendations of the General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures) and the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures) on the SI. Also included is explanatory material, as well as relevant extracts from the International Standards of the International Organization for Standardization (ISO) for the practical use of the SI.
Guide to the SI, with a legal focus:
This notice restates the interpretation of the SI for the United States by the Department of Commerce. As provided by U.S. law, the metric system of measurement to be used in the United States is the SI as established by the General Conference on Weights and Measures and interpreted or modified for the United States by the Secretary of Commerce. The Secretary has delegated this authority to the Director of the National Institute of Standards and Technology.
Diagram of SI unit relationships:
This schematic diagram illustrates how the 22 SI derived units with special names and symbols are related to the seven SI base units. Versions optimized for printing are available.
History of the SI, with a focus on the BIPM
This publication, abbreviated SP 420, gives the history of the first century (1875-1975) of the International Bureau of Weights and Measures (BIPM, Bureau International des Poids et Mesures), including the history of the Convention du Mètre (Meter Convention) and the SI. It is out of print but is available as online PDF.
