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.
NanopascalnPa
Target UnitThe nanopascal (nPa) is a unit of pressure equal to one billionth (10^-9) of a pascal (Pa), which is the SI unit for pressure. It measures the force applied perpendicular to the surface of an object per unit area. The pascal is defined as one newton per square meter. Nanopascals are used in various scientific fields, particularly in environments where extremely low pressures are measured, such as in vacuum technology or in the study of atmospheric phenomena. This unit allows for precise quantification of forces at a micro scale.
Current Use
Today, the nanopascal is utilized primarily in scientific research, particularly in disciplines like meteorology, astrophysics, and vacuum technology. It is essential for measuring minute changes in pressure, such as those encountered in high-altitude atmospheric studies or in creating vacuum environments in laboratories. Instruments capable of detecting pressures at the nanopascal level are crucial for advancements in these fields.
Fun Fact
The nanopascal is so small that it can measure minute changes in atmospheric pressure caused by natural events like earthquakes.

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.
