27.7 inches of H2O is equivalent to how many psi?

To convert inches of water (H2O) to pounds per square inch (psi), you can use the conversion factor that 1 psi is equivalent to approximately 27.7 inches of water. Therefore, to find out how many psi correspond to 27.7 inches of H2O, you would perform the following calculation:

1. 27.7 inches of H2O ÷ 27.7 inches of H2O/psi = 1 psi.

This shows that 27.7 inches of H2O is equal to exactly 1 psi. Understanding this relationship is critical in fields that deal with pressure measurements, as it helps technicians accurately gauge and convert between different pressure units used in various applications.
