Converting Pounds per Square Inch (psi) to Inches of Mercury (inHg) and Vice Versa

Understanding Pressure Measurements

Pressure, a physical quantity that represents the force exerted per unit area, is often expressed in multiple units, including pounds per square inch (psi) and inches of mercury (inHg). These units are commonly used in various scientific and industrial applications, making accurate conversions crucial.

Conversion Formulas

lbs to in/hg

The conversion between psi and inHg involves a simple mathematical relationship:

  • 1 psi = 2.036 inHg
  • 1 inHg = 0.4912 psi

Using the Conversion Formulas

To convert psi to inHg, multiply the psi value by 2.036.

Example:

  • Convert 10 psi to inHg:
10 psi × 2.036 = 20.36 inHg

Conversely, to convert inHg to psi, multiply the inHg value by 0.4912.
