Convert bar to newton/square millimeter
Please provide values below to convert bar [bar] to newton/square millimeter [N/mm^2], or Convert newton/square millimeter to bar.
How to Convert Bar to Newton/square Millimeter
1 bar = 0.1 N/mm^2
Example: convert 15 bar to N/mm^2:
15 bar = 15 × 0.1 N/mm^2 = 1.5 N/mm^2

Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Newton/square Millimeter
Newton per square millimeter (N/mm²) is a unit of pressure or stress, representing the force of one newton applied over an area of one square millimeter.
History/Origin
The unit derives from the SI base unit newton for force and the millimeter for area, commonly used in engineering and material science to measure stress and pressure. It has been in use since the adoption of the SI system, with increased application in fields requiring precise measurement of high pressures.
Current Use
N/mm² is widely used in engineering, material science, and construction to specify material strength, stress, and pressure levels, especially in contexts where high precision is required, such as in the specification of tensile strength and pressure ratings.
