9.99 psi = 0.67978 atm
Full precision:0.67978 atm
Step-by-Step Solution
To convert 9.99 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:
9.99 ÷ 14.6959 = 0.67978 atmospheres
So 9.99 psi = 0.67978 atmospheres.
Quick check: 0.67978 × 14.6959 = 9.99 psi
