If 29.92" Hg is equal to 14.7 psia, then 26" Hg converts to what is psia?

Explanation:
Measuring pressure with inches of mercury scales directly with absolute pressure at a given reference, so the standard is 29.92 inHg = 14.7 psia. To find the psia for 26 inHg, use the proportional relationship: p_psia = 14.7 × (26 / 29.92). This gives 26 / 29.92 ≈ 0.869, and 0.869 × 14.7 ≈ 12.77 psia. So 26 inches of Hg is about 12.77 psia.
