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.
FemtopascalfPa
Target UnitThe femtopascal (fPa) is a unit of pressure in the metric system, representing one quadrillionth (10^-15) of a pascal. The pascal itself is the SI unit of pressure, defined as one newton per square meter. The femtopascal is typically used in scientific contexts where extremely low pressures are encountered, such as in certain high-energy physics experiments, atmospheric studies, and nanotechnology applications. Its precision allows researchers to quantify minuscule pressure variations that would be imperceptible at larger scales.
Current Use
Femtopascals are used primarily in high-precision scientific research, particularly in fields that deal with extremely low pressures, such as astrophysics, material science, and nanotechnology. Instruments designed to measure such minuscule pressures are typically employed in laboratories and specialized research facilities worldwide.
Fun Fact
The femtopascal is so small that it is often used in contexts where pressures are only a fraction of a pascal.

pressure • Non-SI
Definition
Psi 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.
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.

Femtopascal
pressure • Non-SI
Definition
The femtopascal (fPa) is a unit of pressure in the metric system, representing one quadrillionth (10^-15) of a pascal. The pascal itself is the SI unit of pressure, defined as one newton per square meter. The femtopascal is typically used in scientific contexts where extremely low pressures are encountered, such as in certain high-energy physics experiments, atmospheric studies, and nanotechnology applications. Its precision allows researchers to quantify minuscule pressure variations that would be imperceptible at larger scales.
History & Origin
The concept of pressure measurement has ancient roots, but the formal definition of the pascal was established in 1971 during the 14th General Conference on Weights and Measures. The femtopascal emerged later as a necessary subdivision to express lower pressure thresholds encountered in specialized fields.
Etymology: The term 'femto' comes from the Danish word 'femten,' meaning fifteen, indicating the factor of 10^-15. 'Pascal' is named after Blaise Pascal, a French mathematician, physicist, and inventor, who made significant contributions to fluid mechanics and pressure studies.
Current Use

💡 Fun Facts
- •The femtopascal is so small that it is often used in contexts where pressures are only a fraction of a pascal.
- •The pascal itself is a relatively new unit, established only in the 20th century.
- •In scientific literature, the femtopascal is frequently encountered in discussions of the vacuum of space, where pressures are extremely low.
