29.5in = 29.5in(25.4mm/in)(0.001316Atm/mm) = 0.986 Atm
To convert from inches of mercury to atmospheres, you can use the conversion factor of 1 atm = 29.92 inches of mercury.
Step 1: Convert inches of mercury to atmospheres.
29.5 inches / 29.92 inches = 0.986 atm
Therefore, the current pressure in atmospheres is 0.986 atm.
To calculate the current barometric pressure in atmospheres, you need to convert the given pressure from inches of mercury to atmospheres.
The conversion factor is 1 atm = 29.92 inches of mercury.
Thus, you can calculate the pressure in atmospheres by dividing the given pressure in inches of mercury by the conversion factor.
Let's calculate:
29.5 inches of mercury / 29.92 inches of mercury = 0.986 atm
Therefore, the current pressure in atmospheres is 0.986 atm.
