Me a ruckat scyantust???? Heck no. It's all a hoax. The earth is flat. Everyone knows it. If you want to get into space you need to sail south of Tasmania in a wooden square rigger while wearing tar stained wool pants and you will fall right into the ozone hole, never be seen from again. Getting into space isn't the hard part. Getting back is!

Getting backs pretty easy to.
Oh wait, you mean in one piece? yeah that would be a little tricky

Since this is kind of a specialty of mine, here goes: 15*C, 1013.25 hecto pascals (29.92 " Hg) pressure. Metrology is based on 20C

it is for airconditioning for certified laboratories, and CMM rooms ...CMM room staff arent all that fussy tho.....they want to be able to set the temp to what ever they want to be comfortable ...so much for their measurement checking ...oh well its only holden and toyota panels...hahaha..my toyota comes from japan

actually its (standard at 20c) stamped on steel rules

It turns out we are all half right and half wrong.

From Wikipedia.

IUPAC established standard temperature and pressure (informally abbreviated as STP) as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (14.504 psi, 0.986 atm, 1 bar),
An unofficial, but commonly used, standard is standard ambient temperature and pressure (SATP) as a temperature of 298.15 K (25 °C, 77 °F) and an absolute pressure of 100 kPa (14.504 psi, 0.986 atm).
NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 101.325 kPa (14.696 psi, 1 atm).
The International Standard Metric Conditions for natural gas and similar fluids are 288.15 K (59.00 °F; 15.00 °C) and 101.325 kPa."

There are almost as many stps as there are countries.

BobL dropped the nuke. We now have a definitive definition of STP.

I wonder if Science had started in the tropics STP would be higher???
