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.
Kilonewton Square MeterkN·m²
Target UnitThe kilonewton square meter (kN·m²) is a derived unit of pressure that quantifies the force of one kilonewton applied uniformly over an area of one square meter. It is commonly used in engineering and physics to express stress, which is defined as force per unit area. In this context, one kilonewton equals 1,000 newtons, and thus one kN·m² equals 1,000 pascals (Pa), the SI unit of pressure. This unit is essential in fields like civil engineering, material science, and structural analysis, where understanding the distribution of forces across surfaces is critical for safety and design integrity.
Current Use
Kilonewton square meters are widely applied in various industries, particularly in civil engineering, structural engineering, and materials science. This unit helps engineers calculate stress on materials, ensuring that structures can withstand expected loads without failure. Its usage extends to geotechnical engineering for assessing soil pressure under foundations and to mechanical engineering for stress testing of components. Countries that utilize this unit include those following the metric system, primarily in Europe and Asia.
Fun Fact
The kilonewton is often used in calculating the load-bearing capacity of materials, making it crucial in construction.

pressure • Non-SI
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.

Kilonewton Square Meter
pressure • Non-SI
Definition
The kilonewton square meter (kN·m²) is a derived unit of pressure that quantifies the force of one kilonewton applied uniformly over an area of one square meter. It is commonly used in engineering and physics to express stress, which is defined as force per unit area. In this context, one kilonewton equals 1,000 newtons, and thus one kN·m² equals 1,000 pascals (Pa), the SI unit of pressure. This unit is essential in fields like civil engineering, material science, and structural analysis, where understanding the distribution of forces across surfaces is critical for safety and design integrity.
History & Origin
The kilonewton square meter traces its roots back to the International System of Units (SI), which was established in 1960. The concept of pressure as force per area has been utilized since the time of Blaise Pascal in the 17th century. The kilonewton itself, representing a force of 1,000 newtons, became standardized as a convenient measure in engineering to simplify calculations involving heavy loads and structural integrity. The adoption of kilonewtons in place of newtons reflects the large forces often encountered in practical engineering applications, allowing for more manageable numerical values.
Etymology: The term 'kilonewton' derives from the name of Sir Isaac Newton, a foundational figure in classical mechanics, combined with the prefix 'kilo-', which denotes a factor of one thousand.
Current Use
Kilonewton square meters are widely applied in various industries, particularly in civil engineering, structural engineering, and materials science. This unit helps engineers calculate stress on materials, ensuring that structures can withstand expected loads without failure. Its usage extends to geotechnical engineering for assessing soil pressure under foundations and to mechanical engineering for stress testing of components. Countries that utilize this unit include those following the metric system, primarily in Europe and Asia.
💡 Fun Facts
- •The kilonewton is often used in calculating the load-bearing capacity of materials, making it crucial in construction.
- •One kN·m² is equivalent to approximately 0.1 atmosphere, showcasing its relevance in atmospheric pressure measurements.
- •The concept of pressure has applications beyond engineering, including meteorology and fluid dynamics.
