psi to inHg

psi

• Definition: psi stands for pounds per square inch, a unit of pressure used in the United States and some other countries. It measures the force applied to an area of one square inch.

• Symbol: The symbol for pounds per square inch is “psi.”

• Usage: psi is commonly used in various applications, including tire pressure, HVAC systems, and industrial processes that require pressure measurements.

inch of mercury

• Definition: An inch of mercury (inHg) is a unit of pressure defined as the pressure exerted by a column of mercury one inch high at standard gravity.

• Symbol: The symbol for inch of mercury is “inHg.”

• Usage: inch of mercury is often used in barometers and altimeters, as well as in meteorology for measuring atmospheric pressure.

Origin of the psi

• The unit psi originated in the United States and has been widely adopted for various engineering and industrial applications. Its use can be traced back to the need for a practical and easily understandable measurement of pressure in mechanical and hydraulic systems.

Origin of the inch of mercury

• The inch of mercury has its roots in the traditional use of mercury in barometers. It was standardized in the 19th century when it became important for measuring atmospheric pressure, a crucial factor in weather forecasting and aviation.
