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.
CentipascalcPa
Target UnitThe centipascal (cPa) is a unit of pressure in the metric system, defined as one-hundredth of a pascal (Pa). The pascal is the SI derived unit of pressure, defined as one newton per square meter. Therefore, 1 cPa equals 0.01 Pa. This unit is often used in meteorology and other scientific fields where very small pressure changes need to be measured. The centipascal allows for easier expression of these small values without resorting to decimals. It is part of the broader system of units that include the pascal and its multiples.
Current Use
Centipascal is primarily used in scientific research, particularly in meteorology and fluid dynamics, where minute changes in pressure are critical for accurate measurements. It is commonly utilized in barometers, to measure atmospheric pressure, and in various laboratory settings where precise pressure control is essential. Due to its small value, the centipascal provides convenience for expressing slight pressure variations in a more readable format.
Fun Fact
The pascal is named after Blaise Pascal, a French mathematician, physicist, and inventor.

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.

Centipascal
pressure • Non-SI
Definition
The centipascal (cPa) is a unit of pressure in the metric system, defined as one-hundredth of a pascal (Pa). The pascal is the SI derived unit of pressure, defined as one newton per square meter. Therefore, 1 cPa equals 0.01 Pa. This unit is often used in meteorology and other scientific fields where very small pressure changes need to be measured. The centipascal allows for easier expression of these small values without resorting to decimals. It is part of the broader system of units that include the pascal and its multiples.
History & Origin
The concept of pressure measurement can be traced back to the work of Blaise Pascal in the 17th century, who explored the relationship between pressure, force, and area. The unit of pressure named after him, the pascal, was introduced in 1971 as part of the International System of Units (SI). The centipascal is a smaller derivative of the pascal, reflecting the need for measuring minute pressures in various scientific disciplines.
Etymology: The term 'centipascal' derives from the prefix 'centi-', which means one-hundredth, combined with the name 'pascal' in honor of Blaise Pascal.
Current Use
Centipascal is primarily used in scientific research, particularly in meteorology and fluid dynamics, where minute changes in pressure are critical for accurate measurements. It is commonly utilized in barometers, to measure atmospheric pressure, and in various laboratory settings where precise pressure control is essential. Due to its small value, the centipascal provides convenience for expressing slight pressure variations in a more readable format.
