    $\begingroup$ Wikipedia and NIST webbook say 1.1Pa, that has to be correct. $\endgroup$ – Robin Singh Sep 10 at 14:42
  • $\begingroup$ @Safdar The 0.8 Pa value reportedly is from the NIST, however no younger than from 1988. $\endgroup$ – Giovanni Sep 10 at 15:01
  • $\begingroup$ Could the 0.8 value be outdated? $\endgroup$ – Giovanni Sep 10 at 15:02
  • $\begingroup$ @Giovanni NIST reports 1.1 Pa-webbook.nist.gov/cgi/cbook.cgi?ID=C74840&Mask=4. Can you share the link where you found that out? $\endgroup$ – Robin Singh Sep 10 at 15:56
