Dear Folks,

The BIPM has issued a supplement to the SI Brochure. It alters the order of the base units in defining derived units (Tables 6 and 7), it reflects the recent IAU decision to define the astronomical year as a fixed and exact number, and it makes some updates reflecting the latest CODATA, among other things.

Best regards,

Jim Frysinger
