The original source supplies the underlying information. Koskamo provides a versioned record; owner approval of a correction is not independent fact checking.

Keep the unit and stated uncertainty with the value. Records marked exact differ from measured values. The CODATA release is identified in the source; the document update date records publication on Koskamo.
