Atmospheric pressure of 101.3 kPa is approximately how many psi?

Explanation:
Atmospheric pressure at sea level is commonly referenced as 1 atmosphere, which is 101.325 kPa. Converting to psi uses the fact that 1 psi is about 6.895 kPa. So 101.3 kPa divided by 6.895 kPa/psi gives roughly 14.7 psi. That’s why 14.7 psi is the correct approximation. The other values would correspond to quite different pressures (for example, around 29.4 psi is about 2 atm, and 7.3 psi is about 0.5 atm), whereas 101.3 kPa sits right around 14.7 psi.
