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.
All values refer to 25 Â°C and to the thermodynamically stable standard state at that temperature unless noted. Values from CRC refer to 100 kPa (1 bar or 0.987 standard atmospheres). Lange indirectly defines the values to be at a standard state pressure of 1 atm (101325 Pa), although citing the same NBS and JANAF sources among others. It is assumed this inexactly refers to ambient pressure.
