Pressure in "real" unuts: convert atmosphere to Pa

Hi everybody!

Could anyone clarify what is the exact value of the pressure unit in “real” style?

Is it a NIST standard atmosphere (101325 Pa) or IUPAC standard atmosphere (100000 Pa) or maybe technical atmosphere (98066.5 Pa)?

Thank you in advance!

Best regards,
Mikhail

should be the first. you can check it out by looking at the
Update::set_units() function in update.cpp where you find the
conversion factors for n*k_B*T/V to pressure for each choice of units.
