psi
atm
4 psi = 0.27218 atm
Full precision:0.27218 atm
Step-by-Step Solution
To convert 4 psi to atmospheres, we divide by 14.6959 because one atmosphere equals exactly 14.6959 psi.
1 atmosphere = 14.6959 psi
Since there are 14.6959 psi in every atmosphere, we divide our value by this factor:
4 ÷ 14.6959 = 0.27218 atmospheres
So 4 psi = 0.27218 atmospheres.
Quick check: 0.27218 × 14.6959 = 4 psi
