If 29.92" HG equals 14.7 Psia, what is the conversion of 26" HG to Psia?

To convert inches of mercury (Hg) to pounds per square inch absolute (Psia), it's important to understand the relationship between these two units. Atmospheric pressure at sea level is typically defined as 29.92 inches of Hg, which corresponds to 14.7 Psia. This provides a direct ratio for conversion.

First, you can establish the conversion factor from inches of Hg to Psia by setting up a proportional relationship. If 29.92 inches of Hg equals 14.7 Psia, you can convert 26 inches of Hg to Psia using a simple ratio.

To begin the conversion, set up the following proportion:

(26 inches of Hg) / (29.92 inches of Hg) = (X Psia) / (14.7 Psia)

Cross-multiplying to solve for X gives:

X = (26 inches of Hg * 14.7 Psia) / 29.92 inches of Hg

Calculating this provides:

X ≈ 10.5 Psia

By rounding to a more precise value, you find that 26 inches of Hg converts to approximately 12.77 Psia. This means the correct answer reflects an accurate understanding of how to utilize direct conversion ratios in
