Unit Explanations
PascalPa
Source UnitThe pascal (Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. It is defined as one newton per square meter. In other words, it is the pressure exerted by a force of one newton acting uniformly over an area of one square meter. The pascal is a crucial unit in engineering, physics, and meteorology, providing a standard measure for atmospheric pressure, material strength, and force distribution. It allows for consistent and comparable measurements across various scientific and industrial fields.
Current Use
The pascal is widely used in various fields to measure pressure and stress. In meteorology, it is used to express atmospheric pressure, often in the form of hectopascals (hPa). In engineering, it helps evaluate the strength of materials and structures. The unit is also crucial in fluid mechanics, where it is used to determine fluid pressure in pipes and vessels. The pascal's versatility makes it a fundamental unit in both scientific research and practical applications, especially where precise pressure measurements are critical.
Fun Fact
The pascal is named after Blaise Pascal, who made significant contributions to the understanding of fluid pressure.
Pound Force per Square Inchpsi
Target UnitThe pound force per square inch (psi) is a unit of pressure defined as the force of one pound-force (lbf) applied uniformly over an area of one square inch. It is a common unit used in various engineering and scientific applications, particularly in the United States. The pound-force is a force unit derived from the pound, a unit of mass, using the acceleration due to gravity, approximately 32.174 ft/s². Therefore, 1 psi corresponds to a force of about 4.448 Newtons applied over an area of 0.00064516 square meters.
Current Use
Pound force per square inch is predominantly used in the United States for various practical applications, such as tire pressure and hydraulic systems. Many automotive and aerospace industries rely on psi as a standard measurement for pressure gauges. It is also commonly used in everyday products like air compressors and pneumatic tools, making it an essential unit in both professional and domestic settings.
Fun Fact
The psi unit is widely used in the US, while the rest of the world primarily uses pascals (Pa).

It allows for consistent and comparable measurements across various scientific and industrial fields.
History & Origin
The pascal was named in honor of Blaise Pascal, a French mathematician, physicist, and inventor known for his contributions to fluid mechanics and the study of pressure. The unit was officially adopted as the SI unit for pressure in 1971, although the concept of pressure itself dates back to early scientific studies of fluids and gases. The pascal provided a standardized way to measure pressure, replacing a variety of non-standard units previously in use across different regions and industries.
Etymology: The term 'pascal' is derived from the name of Blaise Pascal.

Pound Force per Square Inch
pressure • Non-SI
Definition
The pound force per square inch (psi) is a unit of pressure defined as the force of one pound-force (lbf) applied uniformly over an area of one square inch. It is a common unit used in various engineering and scientific applications, particularly in the United States. The pound-force is a force unit derived from the pound, a unit of mass, using the acceleration due to gravity, approximately 32.174 ft/s². Therefore, 1 psi corresponds to a force of about 4.448 Newtons applied over an area of 0.00064516 square meters.
History & Origin
The concept of measuring pressure has ancient roots, with early civilizations using rudimentary methods to gauge force applied over areas. The specific unit psi emerged in the 19th century as engineers and scientists sought standardized measures for pressure in various applications, including hydraulics and pneumatics. The integration of the pound-force and the square inch into a single unit allowed for easier calculations and engineering practices, particularly in industries heavily influenced by British and American standards.
Etymology: The term 'pound' originates from the Latin word 'pondus,' meaning weight, while 'force' refers to the influence that causes an object to change its velocity, derived from the Latin 'fortis,' meaning strong. 'Square inch' combines the unit of area from the Latin 'area,' which denotes a level surface.
Current Use
Pound force per square inch is predominantly used in the United States for various practical applications, such as tire pressure and hydraulic systems. Many automotive and aerospace industries rely on psi as a standard measurement for pressure gauges. It is also commonly used in everyday products like air compressors and pneumatic tools, making it an essential unit in both professional and domestic settings.
💡 Fun Facts
- •The psi unit is widely used in the US, while the rest of the world primarily uses pascals (Pa).
- •One psi is equivalent to approximately 6894.76 pascals, illustrating the difference between imperial and metric systems.
- •The tire pressure monitoring systems in vehicles often alert drivers when tire pressure falls below a certain psi threshold, enhancing safety.
