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.
Gram Force per Square Centimetergf/cm²
Target UnitGram force per square centimeter (gf/cm²) is a unit of pressure defined as the pressure exerted by a force of one gram acting on an area of one square centimeter. It is derived from the force of gravity acting on a mass and is used to quantify the force exerted on a surface area. Given that the acceleration due to gravity is approximately 9.80665 m/s², one gram force translates to a pressure of approximately 0.980665 N/cm². This unit, while not part of the SI system, is commonly encountered in various fields, particularly in materials testing and engineering applications.
Current Use
Currently, gram force per square centimeter is used primarily in engineering and material science, particularly in testing the tensile strength and compressive strength of materials. Its practical application allows engineers and scientists to easily communicate pressure values in contexts where small forces are involved, such as in the textile industry or in quality control processes. Although it is not an SI unit, its use persists in certain regions and industries where it is more intuitive.
Fun Fact
The gram force is often used in practical applications because it relates directly to everyday weights, making it intuitive for non-engineers.

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.
💡 Fun Facts
- •The bar is almost exactly the atmospheric pressure on Earth at sea level.
- •The unit 'bar' is not an SI unit, but it's accepted for use with SI due to its practicality.
- •The word 'barometer', an instrument for measuring atmospheric pressure, shares its root with the unit 'bar'.

Gram Force per Square Centimeter
pressure • Non-SI
Definition
Gram force per square centimeter (gf/cm²) is a unit of pressure defined as the pressure exerted by a force of one gram acting on an area of one square centimeter. It is derived from the force of gravity acting on a mass and is used to quantify the force exerted on a surface area. Given that the acceleration due to gravity is approximately 9.80665 m/s², one gram force translates to a pressure of approximately 0.980665 N/cm². This unit, while not part of the SI system, is commonly encountered in various fields, particularly in materials testing and engineering applications.
History & Origin
The gram force per square centimeter has its roots in the need to measure pressure in a practical and manageable way, particularly in contexts where forces are small and areas are limited. It arose as a means to express pressure in terms of mass and surface area, making it easier to relate to everyday experiences. The concept of gram force emerged in the late 19th century as scientists and engineers sought to quantify forces in relation to gravitational acceleration.
Etymology: The term 'gram' comes from the Late Latin 'gramma', which means a small weight, and 'force' indicates the influence that causes an object to undergo a change, in motion or shape. 'Square centimeter' refers to an area measurement, indicating a square with sides of one centimeter.
Current Use
Currently, gram force per square centimeter is used primarily in engineering and material science, particularly in testing the tensile strength and compressive strength of materials. Its practical application allows engineers and scientists to easily communicate pressure values in contexts where small forces are involved, such as in the textile industry or in quality control processes. Although it is not an SI unit, its use persists in certain regions and industries where it is more intuitive.
💡 Fun Facts
- •The gram force is often used in practical applications because it relates directly to everyday weights, making it intuitive for non-engineers.
- •In some countries, the use of gram force per square centimeter is still prevalent despite the global push towards SI units.
- •One gram force per square centimeter is approximately equivalent to 98.0665 pascals, showing its relation to the more commonly used SI unit.
