Unit Explanations
Barbar
Source UnitThe bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.
Current Use
The bar is widely used in various fields including meteorology for atmospheric pressure, and in industries such as automotive and aviation for tire pressure and cabin pressure monitoring. It is especially favored in contexts where moderate pressures need to be measured with a single-digit number, avoiding the unwieldy values that would result from using pascals.
Fun Fact
The bar is almost exactly the atmospheric pressure on Earth at sea level.
Newton Square MeterNĀ·mĀ²
Target UnitThe newton square meter (NĀ·mĀ²) represents a unit of pressure, defined as the amount of force (in newtons) applied uniformly over an area of one square meter. In the SI system, pressure is defined as force per unit area, and therefore 1 NĀ·mĀ² is equivalent to 1 pascal (Pa). This unit is frequently used in various scientific and engineering applications where precise measurements of force distributed over a surface area are necessary, such as fluid mechanics, solid mechanics, and thermodynamics.
Current Use
Currently, the newton square meter is predominantly used in scientific and engineering contexts, particularly in the fields of fluid dynamics, material science, and structural engineering. It is crucial for calculating stress, strain, and other related physical properties of materials. The unit helps in standardizing measurements across different disciplines, ensuring consistency and accuracy in reporting pressure.
Fun Fact
The pascal, which is equivalent to the newton square meter, is named after Blaise Pascal, who made significant contributions to fluid mechanics.

Definition
The bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.
History & Origin
The bar as a unit of pressure was introduced in the early 20th century. It was created to provide a convenient metric unit for expressing pressures without having to resort to using large numbers, as can occur with the pascal. The bar was defined in 1909 by the International Union of Pure and Applied Chemistry (IUPAC) to be equivalent to 100,000 pascals, simplifying conversion with the SI system.
Etymology: The word 'bar' comes from the Greek word 'baros', meaning weight.
Current Use
The bar is widely used in various fields including meteorology for atmospheric pressure, and in industries such as automotive and aviation for tire pressure and cabin pressure monitoring. It is especially favored in contexts where moderate pressures need to be measured with a single-digit number, avoiding the unwieldy values that would result from using pascals.

Newton Square Meter
pressure ā¢ Non-SI
Definition
The newton square meter (NĀ·mĀ²) represents a unit of pressure, defined as the amount of force (in newtons) applied uniformly over an area of one square meter. In the SI system, pressure is defined as force per unit area, and therefore 1 NĀ·mĀ² is equivalent to 1 pascal (Pa). This unit is frequently used in various scientific and engineering applications where precise measurements of force distributed over a surface area are necessary, such as fluid mechanics, solid mechanics, and thermodynamics.
History & Origin
The newton square meter originated in the context of pressure measurement, which has evolved over centuries. The concept of pressure, defined as force per unit area, was formalized in the 17th century with the work of physicists like Blaise Pascal. The newton, as a force unit, was defined in 1687 by Sir Isaac Newton in his seminal work, 'PhilosophiƦ Naturalis Principia Mathematica'. The square meter was established as the SI unit of area in 1960.
Etymology: The term 'newton' is named after Sir Isaac Newton, honoring his contributions to physics, particularly his laws of motion. The term 'square meter' derives from the geometric definition of a meter squared, representing an area.
Current Use
Currently, the newton square meter is predominantly used in scientific and engineering contexts, particularly in the fields of fluid dynamics, material science, and structural engineering. It is crucial for calculating stress, strain, and other related physical properties of materials. The unit helps in standardizing measurements across different disciplines, ensuring consistency and accuracy in reporting pressure.
