Human density edit
Shouldn't the average human density be 0.9xx kg/m^3? Since humans are capable of floating in water I doubt the density will be close to 1000.--2ltben 03:22, 1 September 2006 (UTC)
No Water is about 1000456 kg/m3 as it is about 1 kg/litre. I believe an early definition of a kg was the "weight" (mass) of a litre of water. Crysta1c1ear 19:53, 28 December 2006 (UTC)
I found a 1966 US government study on human body density (well, my gf found it). I averaged the densities in Table 1 to come up with 1062 kg/m3 instead of the previously quoted and uncited value of 1010 kg/m3. This study contains no data for females, but I figured a documented value that only accounts for males is better than an undocumented value. I assume that the difference in density would not be significant between males and females. Also, it should be noted that this study has a rather small sample size (14 people), but again, a documented number is better than an undocumented one, or at least that was my philosophy.

Iridium edit
There seems to be uncertainty about the actual density of iridium and how it was calculated. See the article on iridium for the info.
Best vacuum from a laboratory (1 pPa) edit
Is two orders of magnitude too low. 10e-14 torr is about 80 pPa which is sth like 1e-16 Pa. Not sure how to edit tables so sorry for not correcting it myself. — Preceding unsigned comment added by 94.173.154.109 (talk) 20:41, 22 April 2015 (UTC)
