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.
PicopascalpPa
Target UnitThe picopascal (pPa) is a subunit of pressure in the International System of Units (SI), defined as one trillionth (10^-12) of a pascal (Pa). The pascal, named after the French mathematician and physicist Blaise Pascal, is the SI unit of pressure, defined as one newton per square meter. The picopascal, therefore, provides a means to express extremely low pressures, which are often encountered in high-vacuum physics and certain environmental measurements, making it crucial for scientific and technical applications where precision is paramount.
Current Use
Today, the picopascal is widely used in fields requiring precise measurements of low pressure, such as in vacuum technology, meteorology, and aerospace. Instruments capable of measuring pressures in picopascals are essential for experiments in high-energy physics and for monitoring environmental conditions at altitudes where atmospheric pressure is extremely low.
Fun Fact
The picopascal is so small that it can measure pressures in conditions such as space, where traditional units would be impractical.

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.

Picopascal
pressure • Non-SI
Definition
The picopascal (pPa) is a subunit of pressure in the International System of Units (SI), defined as one trillionth (10^-12) of a pascal (Pa). The pascal, named after the French mathematician and physicist Blaise Pascal, is the SI unit of pressure, defined as one newton per square meter. The picopascal, therefore, provides a means to express extremely low pressures, which are often encountered in high-vacuum physics and certain environmental measurements, making it crucial for scientific and technical applications where precision is paramount.
History & Origin
The picopascal was introduced in the context of the metric system as a means to express very low pressure values, which became essential for modern physics and engineering. The pascal, as the base unit, was adopted in 1971 during the 14th CGPM, and subunits like the picopascal followed as the need for more precise measurements in low-pressure scenarios increased, particularly in the fields of meteorology and vacuum technology.
Etymology: The term 'pico' is derived from the Spanish word for 'small', and in scientific terminology, it denotes a factor of 10^-12. Thus, 'picopascal' directly translates to one trillionth of a pascal.
Current Use
Today, the picopascal is widely used in fields requiring precise measurements of low pressure, such as in vacuum technology, meteorology, and aerospace. Instruments capable of measuring pressures in picopascals are essential for experiments in high-energy physics and for monitoring environmental conditions at altitudes where atmospheric pressure is extremely low.
💡 Fun Facts
- •The picopascal is so small that it can measure pressures in conditions such as space, where traditional units would be impractical.
- •One picopascal is equivalent to 0.000000000001 pascals, showcasing the extreme precision required in specific scientific applications.
- •The concept of picopascal is not only used in physics but also in geosciences for measuring low ground pressure variations.
