One inch of mercury is equal to how many psi?

Explanation:
Converting pressure between inches of mercury and psi hinges on the relationship: 1 atmosphere equals 29.92 inches of mercury and also about 14.7 psi. Using that, 1 inch of mercury equals 14.7 psi divided by 29.92, which is roughly 0.491 psi. Rounding to a practical value gives about 0.5 psi. That’s why the best answer is the one stating 0.5 psi. The other numbers are not close to the actual conversion—0.25 psi is about half, while 1.0 and 2.0 psi are much greater than the true conversion.
