Millimeter Water (4°c)

Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.

History/Origin

The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.

Current Use

It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.


Pound-Force/square Inch

Pound-force per square inch (lbf/in^2) is a unit of pressure representing the force of one pound-force applied over an area of one square inch.

History/Origin

The unit originated from the Imperial system and became widely used in the United States for measuring pressure, especially in engineering and tire pressure contexts.

Current Use

Today, lbf/in^2, commonly known as psi, is still used in various fields such as automotive, aerospace, and industrial applications to measure pressure.
