Convert 10 psi to inches of water

Explanation

Let's convert 10 pounds per square inch to inches of water, or psi to inH₂O as one could put it.

First, we need to calculate the conversion factor using the units respective values. We find 27.6799.

Then we multiply this conversion factor by the number of pounds per square inch. In this case 10.

Therefore, 10 pounds per square inch is approximately equal to 276.799 inches of water.

Formula

1 psi≈27.6799 inH₂O

10 psi≈10 × 27.6799 inH₂O

10 psi≈276.799 inH₂O
