Inch of Mercury (inHg) to Pounds per Square Inch (psi) Pressure Unit Conversion Calculator

This calculator allows you to convert pressure values from Inch of Mercury (inHg) to Pounds per Square Inch (psi), which are commonly used in weather forecasting, aviation, and various industrial applications requiring precise pressure measurements.

Definition: Inch of Mercury (inHg)

The Inch of Mercury (inHg) is a unit of pressure that represents the pressure exerted by a 1-inch column of mercury at 0°C under standard gravity. It is often used in barometric pressure measurements and various industrial processes.

Definition: Pounds per Square Inch (psi)

Pounds per Square Inch (psi) is an imperial unit of pressure commonly used in the United States to measure pressure in systems like tires, hydraulics, and pipelines. It indicates the pressure resulting from a force of one pound-force applied to an area of one square inch.

Formula for inHg to psi Conversion

Pressure in psi=Pressure in inHg×0.491154

How to Convert inHg to psi: Example Calculation

Suppose you have a pressure of 30 inHg. To convert it to psi:

30 inHg×0.491154=14.73462 psi

So, 30 inHg is approximately equal to 14.73 psi.
