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.
Ton Force per Square Inchtf/in²
Target UnitThe ton force per square inch (tf/in²) is a unit of pressure that quantifies the force of one long ton (approximately 1016 kg) exerted uniformly over an area of one square inch. This unit is used primarily in the United Kingdom and industries that still rely on imperial measurements. It serves as a measure of stress and pressure in various mechanical and civil engineering applications, particularly where heavy machinery or structural loads are concerned. The ton force is based on gravitational force at sea level, making this unit critical for applications where weight and area interact.
Current Use
Today, the ton force per square inch is primarily used in engineering and construction industries, particularly in the UK and Commonwealth countries. It is employed in the design and analysis of structural components, machinery, and vehicles, where understanding the pressure exerted by loads is crucial for safety and performance. It remains relevant in applications involving heavy machinery, such as cranes and bulldozers, where load distribution and pressure on surfaces need to be carefully managed.
Fun Fact
The long ton is equivalent to 1,016 kilograms, making it heavier than the short ton used in the United States.

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'.

Ton Force per Square Inch
pressure • Non-SI
Definition
The ton force per square inch (tf/in²) is a unit of pressure that quantifies the force of one long ton (approximately 1016 kg) exerted uniformly over an area of one square inch. This unit is used primarily in the United Kingdom and industries that still rely on imperial measurements. It serves as a measure of stress and pressure in various mechanical and civil engineering applications, particularly where heavy machinery or structural loads are concerned. The ton force is based on gravitational force at sea level, making this unit critical for applications where weight and area interact.
History & Origin
The concept of a ton as a unit of weight dates back to medieval Europe, where it represented a measure of mass based on the capacity of a barrel or cask. The long ton is defined as 1,016 kilograms, which was standardized in the UK in the 19th century. The use of square inches as a measure of area can be traced to the imperial system of measurement, widely adopted for engineering and construction purposes. The combination of these two units into a pressure measurement reflects the practical needs of industries dealing with heavy loads and materials.
Etymology: The word 'ton' is derived from the Latin 'tonnus,' meaning a large cask or barrel. The term 'square inch' comes from the Latin 'inch' and the Old French 'unche,' denoting a small linear measure, combined with 'square' to indicate area.
Current Use
Today, the ton force per square inch is primarily used in engineering and construction industries, particularly in the UK and Commonwealth countries. It is employed in the design and analysis of structural components, machinery, and vehicles, where understanding the pressure exerted by loads is crucial for safety and performance. It remains relevant in applications involving heavy machinery, such as cranes and bulldozers, where load distribution and pressure on surfaces need to be carefully managed.
💡 Fun Facts
- •The long ton is equivalent to 1,016 kilograms, making it heavier than the short ton used in the United States.
- •Despite the metrication efforts, the ton force per square inch is still widely used in the UK, especially in engineering.
- •One ton force per square inch is approximately equal to 6,894.76 pascals.
