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.
GigapascalGPa
Target UnitThe gigapascal (GPa) is a derived unit of pressure in the International System of Units (SI) equal to one billion pascals (Pa). It is commonly used to express high pressures in materials science, geophysics, and engineering applications. One pascal is defined as one newton per square meter, which establishes the gigapascal as a substantial unit for measuring stress, pressure, or tensile strength in various materials, particularly in structural and mechanical engineering.
Current Use
Today, the gigapascal is widely used in various industries, including civil engineering, aerospace, and automotive sectors, for measuring material strength and resilience under stress. It is also significant in geological studies, where subsurface pressures are crucial for oil and gas exploration. Countries with advanced manufacturing capabilities, such as the United States, Germany, and Japan, frequently utilize gigapascals in their engineering and research practices to ensure safety and efficiency in material applications.
Fun Fact
The gigapascal is often used in the context of testing materials for aerospace applications due to the extreme conditions they encounter.

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.
