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.
Newton per Square MillimeterN/mm²
Target UnitThe newton per square millimeter (N/mm²) is a metric unit of pressure that measures the amount of force applied per unit area. It is derived from the SI unit of force, the newton (N), and the area unit, the square millimeter (mm²). One newton represents the force required to accelerate one kilogram of mass at a rate of one meter per second squared. The newton per square millimeter is often used in engineering and material science to express tensile strength, yield strength, and other mechanical properties of materials.
Current Use
Today, the newton per square millimeter is widely used in engineering, particularly in the fields of material science and structural engineering. It is common in specifications for materials, especially metals and polymers, to indicate their tensile strength and compressive strength. This unit is particularly useful in assessing the mechanical properties of materials used in construction, automotive, and aerospace industries, where precise measurements are critical for safety and performance.
Fun Fact
A newton per square millimeter is equivalent to 1 megapascal (MPa), which is a common unit in engineering.

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.

Newton per Square Millimeter
pressure • Non-SI
Definition
The newton per square millimeter (N/mm²) is a metric unit of pressure that measures the amount of force applied per unit area. It is derived from the SI unit of force, the newton (N), and the area unit, the square millimeter (mm²). One newton represents the force required to accelerate one kilogram of mass at a rate of one meter per second squared. The newton per square millimeter is often used in engineering and material science to express tensile strength, yield strength, and other mechanical properties of materials.
History & Origin
The newton was named after Sir Isaac Newton in the late 19th century, recognizing his contributions to classical mechanics. It became part of the metric system as the standard unit for force, while the square millimeter is a metric area unit derived from the millimeter, which has been in use since the metric system was established in the late 18th century. The combination of these two units to form N/mm² has allowed for a practical means of expressing pressure in various scientific and engineering applications.
Etymology: The term 'newton' is derived from the Latin 'Newtonius', and the prefix 'milli-' indicates a factor of one-thousandth in metric measurements.
