inHg to N/m²

inch of mercury

• Definition: Inch of mercury (inHg) is a unit of pressure that measures how high a column of mercury can be supported by atmospheric pressure. It is commonly used in meteorology and various engineering applications.

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

• Usage: Inch of mercury is primarily used in barometers, altimeters, and other instruments that measure atmospheric pressure. It is also used in HVAC systems and other engineering fields.

newton per square meter

• Definition: Newton per square meter (N/m²), also known as pascal (Pa), is the SI unit of pressure. It quantifies the amount of force applied over a unit area.

• Symbol: The symbol for newton per square meter is “N/m².”

• Usage: Newton per square meter is used in various scientific and engineering contexts, including fluid mechanics, material science, and pressure measurements in industrial applications.

Origin of the inch of mercury

• The inch of mercury originated from the history of barometric pressure measurement. The first barometers were developed in the 17th century, and mercury was used due to its high density. The use of inches as a unit came from British imperial measurement systems, making it a standard for atmospheric pressure readings in many regions.

Origin of the newton per square meter

• The newton per square meter is derived from the SI unit of force, the newton, which is named after Sir Isaac Newton. The unit was established to provide a coherent and standardized way to measure pressure in scientific contexts. The pascal, defined as one newton per square meter, is widely used in various fields of science and engineering.
