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.
Atmosphere (Technical)atm
Target UnitThe technical atmosphere (atm) is a unit of pressure defined as being precisely equal to 101325 pascals (Pa). It is widely used in various scientific and engineering applications, particularly in fields such as meteorology, aviation, and chemistry. The atmosphere is a convenient measure of pressure that reflects the average atmospheric pressure at sea level. It is not an SI unit, but it is accepted for use with the SI system. The unit is commonly used in calculations involving gas laws, fluid dynamics, and other applications where pressure measurement is critical.
Current Use
The technical atmosphere is primarily used in fields such as meteorology, aviation, and engineering. It serves as a reference pressure in various calculations, such as those involving the behavior of gases under different conditions. It is also used in the calibration of pressure gauges and barometers, ensuring consistency in pressure measurements across different instruments and applications.
Fun Fact
The atmosphere is defined to be equivalent to 101325 pascals, but it can also be expressed in other units, such as mmHg and bar.

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.
