This couple posted their budget with every single line item for living in Puerto Vallarta for the year of 2014. That gives us a baseline estimate for what it would cost. Their annual cost was $40,470, though they suggest it would be possible to get by on $13,500 if absolutely necessary.
Now, letâs move on to the atmosphere or atm unit. The standard atmosphere unit is assumed constant. It is equal to the typical air pressure measured at the earth mean sea level. One standard atmosphere or atm is equal to 101,325 pascals or 101.325 kPa or 1,013.35 hPa.
Matthew Bennett, BSc in Physics from UC in Christchurch, New Zealand. Views. Atmospheric pressure at sea level is approximately 100,000 pascals (101,325 Pa by definition.) Air pressure is usually measured in hectopascals (hPa), the hecto prefix corrsponding to 100 (a hecatre is a square with 100m sides), so 1 atmosphere is approximately 1000 hPa. A pascal is the SI unit for pressure, defined as 1 newton per square metre.
