Frequently asked questions
What is the source unit in this conversion?
The source unit is the psi (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the inhg (inHg). Inches of mercury.
How do I convert psi to inhg?
Multiply the psi value by 2.03602. For example, 10 psi × 2.03602 = 20.360205 inHg.
Is the psi to inhg conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in psi needs to be compared with, or reported in, inhg, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert inhg back to psi?
Yes. Multiply the inhg value by 0.491154 to get psi.

About this conversion
This page converts psi (psi) to inhg (inHg) within the pressure converter.
Pounds per square inch. Inches of mercury.
The formula is inhg = psi × 2.03602, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
