WP 34S Unit conversion question

[rkf]

Strange, indeed. The predecessor to NIST, the National Bureau of Standards, yet gave the conversion 1 pound = 0.45359237 kg, see this publication on todays NIST public server. Obviously, anywhere in between the rounding took place.

Just for curiosity I sent a mail to the NIST webmaster asking for an explanation. I'll keep you informed :-)

Kind regards,
Ralf.
