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.
ExapascalEPa
Target UnitThe exapascal (EPa) is a derived unit of pressure in the International System of Units (SI), representing one quintillion pascals (10^18 Pa). It is employed to express extremely high pressures, often found in theoretical physics and advanced engineering scenarios. The pascal itself is defined as one newton per square meter, making the exapascal a significant scale for measuring pressure in environments such as planetary atmospheres or during high-energy physics experiments.
Current Use
Currently, the exapascal is primarily used in scientific research and theoretical studies where exceptionally high pressures are encountered. This includes fields such as astrophysics, where pressures within stars or black holes exceed traditional measurements. Additionally, certain engineering applications, including materials testing under extreme conditions, may utilize the exapascal to describe stress on materials.
Fun Fact
The exapascal is not commonly used in everyday applications, making it a unit primarily of theoretical interest.

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.

Exapascal
pressure • Non-SI
Definition
The exapascal (EPa) is a derived unit of pressure in the International System of Units (SI), representing one quintillion pascals (10^18 Pa). It is employed to express extremely high pressures, often found in theoretical physics and advanced engineering scenarios. The pascal itself is defined as one newton per square meter, making the exapascal a significant scale for measuring pressure in environments such as planetary atmospheres or during high-energy physics experiments.
History & Origin
The exapascal was introduced as part of the SI units to facilitate the expression of extremely large pressure values. It emerged from the need to quantify pressures encountered in specialized fields like astrophysics and materials science. The pascal, the base unit of pressure, was named after Blaise Pascal, a French mathematician, physicist, and inventor, who made significant contributions to fluid mechanics and hydrostatics.
Etymology: The term 'exa' is derived from the Greek word 'hex' meaning six, and denotes the factor of 10^18 in the metric system.
Current Use
Currently, the exapascal is primarily used in scientific research and theoretical studies where exceptionally high pressures are encountered. This includes fields such as astrophysics, where pressures within stars or black holes exceed traditional measurements. Additionally, certain engineering applications, including materials testing under extreme conditions, may utilize the exapascal to describe stress on materials.
💡 Fun Facts
- •The exapascal is not commonly used in everyday applications, making it a unit primarily of theoretical interest.
- •An exapascal is equivalent to the pressure exerted by a mass of about 100 million tons on a surface area of one square meter.
- •The prefix 'exa' is rarely used in practical scenarios, highlighting the extreme conditions under which the exapascal is applicable.
