What is the atmospheric pressure at sea level expressed in psi?

Explanation:
At sea level the pressure is defined as one atmosphere, which equals about 101,325 pascals. In psi, that converts to roughly 14.696 psi, commonly rounded to 14.7 psi. The other numbers don’t fit because 0 psi would indicate a vacuum, about 32 psi is around 2.2 atm, and 212 psi is far higher than standard sea-level pressure. So the best answer is 14.7 psi.
