Unit Explanations
Pounds per Square Inchpsi
Source UnitPsi or 'pounds per square inch' is a unit used to measure pressure. It defines the pressure resulting from a force of one pound-force applied to an area of one square inch. As a non-SI unit, it is commonly used in the United States and other countries still employing the Imperial system. Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
Current Use
Today, psi is extensively used in various fields, particularly in the United States. It is prevalent in automotive applications, where it measures tire pressure, ensuring safety and performance. Additionally, psi is crucial in aerospace, measuring cabin pressure and hydraulic systems. In industrial settings, it is used for pressure gauges, compressors, and pneumatic tools. Despite the global trend towards SI units, psi's practical relevance maintains its usage in specific regions and industries.
Fun Fact
Psi is still a preferred unit in U.S. automotive manuals.
Centimeter of MercurycmHg
Target UnitThe centimeter of mercury (cmHg) is a unit of pressure that corresponds to the height of a column of mercury 1 centimeter in height under the influence of standard gravity. It is commonly used in various scientific and engineering applications to measure pressure. The standard atmospheric pressure is defined as 76 cmHg. This unit is derived from the physical principle that the pressure exerted by a fluid in an open system is proportional to the height of the fluid column above it. Hence, 1 cmHg is approximately equal to 98.0665 pascals.
Current Use
The centimeter of mercury is widely used in meteorology, automotive industries, and scientific laboratories to measure atmospheric pressure and partial pressures of gases. It is particularly useful in creating barometers and altimeters, providing a practical and precise way to quantify pressure changes. In many countries, cmHg is a common unit for displaying tire pressure and other applications where pressure measurement is critical.
Fun Fact
The centimeter of mercury is often used as a reference for comparing pressures in different contexts, such as altimeters and weather reports.

Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
History & Origin
The psi unit emerged from the need to measure pressure in the Imperial system, prevalent in the United States and other regions before the widespread adoption of the metric system. It is a derivative unit representing the pressure exerted by a force of one pound-force on a square inch of surface area. The concept of pressure measurement has evolved over time, with psi becoming a standard term in industries reliant on precise pressure control.
Etymology: The term 'psi' stands for 'pounds per square inch,' combining 'pound,' a unit of force, and 'square inch,' a unit of area.

Hence, 1 cmHg is approximately equal to 98.0665 pascals.
History & Origin
The centimeter of mercury emerged from the need to measure atmospheric pressure, particularly in the context of barometers. Early barometers used mercury due to its high density and low vapor pressure, allowing for a manageable column height to represent atmospheric pressure. The concept of measuring pressure using a liquid column dates back to the 17th century, when Evangelista Torricelli demonstrated that atmospheric pressure can support a column of mercury.
Etymology: The term 'centimeter' is derived from the French 'centimètre', combining 'centi-', meaning one-hundredth, and 'mètre', meaning meter. 'Mercury' comes from the Latin 'hydrargyrum', referring to the element's fluid metallic form.

💡 Fun Facts
- •The centimeter of mercury is often used as a reference for comparing pressures in different contexts, such as altimeters and weather reports.
- •Mercury is used in barometers because it has a high density, allowing for a shorter column to represent atmospheric pressure.
- •In many regions, pressure is often measured in cmHg for both practical and historical reasons, despite the metric system's global adoption.
