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.
Kilogram Force per Square Millimeterkgf/mm²
Target UnitThe kilogram force per square millimeter (kgf/mm²) is a unit of pressure that expresses the force exerted by a mass of one kilogram under standard gravity (9.80665 m/s²) acting uniformly over an area of one square millimeter. This unit is commonly used in various fields of engineering and materials science to quantify stress, particularly in metallurgy, where materials are tested for their strength and durability under different load conditions. The relationship between kgf/mm² and other pressure units is critical for conversions, especially in scientific applications.
Current Use
Today, the kilogram force per square millimeter is predominantly used in engineering and manufacturing sectors, particularly in the testing and evaluation of material strength. It helps engineers calculate the stress that materials can withstand during various types of loading conditions. It remains relevant in countries that utilize the metric system, particularly in Europe and Asia, where it is often used alongside other metric pressure units.
Fun Fact
The kilogram force per square millimeter is equivalent to 9.80665 megapascals (MPa).

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.

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.

Kilogram Force per Square Millimeter
pressure ⢠Non-SI
Definition
The kilogram force per square millimeter (kgf/mm²) is a unit of pressure that expresses the force exerted by a mass of one kilogram under standard gravity (9.80665 m/s²) acting uniformly over an area of one square millimeter. This unit is commonly used in various fields of engineering and materials science to quantify stress, particularly in metallurgy, where materials are tested for their strength and durability under different load conditions. The relationship between kgf/mm² and other pressure units is critical for conversions, especially in scientific applications.
History & Origin
The kilogram force per square millimeter emerged in the early 20th century as engineers and scientists sought a practical unit for measuring pressure and stress in materials. The use of mass and gravitational force as a basis for this unit reflects the common practice in engineering to relate physical properties to everyday weights. Its adoption was facilitated by the widespread use of the metric system, which provided a standardized approach to measurements.
Etymology: The term 'kilogram' comes from the French 'kilogramme', which itself is derived from the Greek 'khilioi' (a thousand) and the French 'gramme' (a small weight). 'Force' refers to the push or pull exerted on an object, derived from Latin 'fortis'. 'Square millimeter' combines 'square', indicating area, from Latin 'squarere', and 'millimeter', which means one-thousandth of a meter, from the prefix 'milli-' and 'meter' from Greek 'metron', meaning measure.
Current Use
Today, the kilogram force per square millimeter is predominantly used in engineering and manufacturing sectors, particularly in the testing and evaluation of material strength. It helps engineers calculate the stress that materials can withstand during various types of loading conditions. It remains relevant in countries that utilize the metric system, particularly in Europe and Asia, where it is often used alongside other metric pressure units.
đĄ Fun Facts
- â˘The kilogram force per square millimeter is equivalent to 9.80665 megapascals (MPa).
- â˘In some engineering contexts, kgf/mm² is preferred due to its direct relation to the weight of materials and practical applications.
- â˘The unit reflects a blend of gravitational force and area measurement, making it intuitive for those familiar with mass in kilograms.
