Unit Explanations
Pounds per Square Inchpsi
Source UnitPsi or 'pounds per square inch' is a unit used to measure pressure. It defines the pressure resulting from a force of one pound-force applied to an area of one square inch. As a non-SI unit, it is commonly used in the United States and other countries still employing the Imperial system. Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
Current Use
Today, psi is extensively used in various fields, particularly in the United States. It is prevalent in automotive applications, where it measures tire pressure, ensuring safety and performance. Additionally, psi is crucial in aerospace, measuring cabin pressure and hydraulic systems. In industrial settings, it is used for pressure gauges, compressors, and pneumatic tools. Despite the global trend towards SI units, psi's practical relevance maintains its usage in specific regions and industries.
Fun Fact
Psi is still a preferred unit in U.S. automotive manuals.
Kilogram Force Square Meterkgf·m²
Target UnitThe kilogram force square meter (kgf·m²) is a unit of pressure that expresses the force applied by one kilogram-force acting uniformly over an area of one square meter. It is a non-SI unit derived from the kilogram (kg), a unit of mass, and the meter (m), a unit of length. The kilogram-force is the force exerted by a mass of one kilogram in a gravitational field of standard gravity (9.80665 m/s²). Therefore, a pressure of one kgf·m² is equivalent to 9.80665 pascals (Pa), where pascal is the SI unit of pressure.
Current Use
Today, the kilogram force square meter is primarily used in engineering and physical sciences, particularly in the fields of mechanics and hydraulics. It facilitates the understanding of force distribution across surfaces, aiding in the design of structures and machinery. While the SI unit pascal is more universally accepted, the kgf·m² is still relevant in certain industries that prefer traditional measurements or are based in regions where imperial units are prevalent.
Fun Fact
The kilogram-force is sometimes used interchangeably with the newton in engineering, despite being based on different principles.

Therefore, a pressure of one kgf·m² is equivalent to 9.80665 pascals (Pa), where pascal is the SI unit of pressure.
History & Origin
The kilogram force square meter emerged in the late 19th century alongside the development of the metric system. As scientists and engineers sought standardized units to measure mechanical systems, the need for pressure units became apparent. The kilogram-force was adopted to simplify the calculations involving gravitational forces, particularly in engineering applications. Over time, it became a common reference in various fields, including hydraulics and fluid mechanics.
Etymology: The term 'kilogram' is derived from the Greek word 'kilo' meaning 'thousand', and 'gram' from the Greek 'gramma' meaning 'small weight'. 'Force' originates from the Latin 'fortis', meaning strong. The word 'meter' comes from the Greek 'metron', meaning measure.
