Unit Explanations
Kilometer Square Secondkm²/s
Source UnitThe kilometer square second (km²/s) is a derived unit of acceleration that describes how an object moves over a distance of one square kilometer in one second. This unit conveys the rate of change of velocity that an object experiences in a two-dimensional plane. It can be expressed as the distance traveled (in square kilometers) divided by the square of the time taken (in seconds). Acceleration is a vector quantity, indicating both magnitude and direction, and applies to various fields such as physics, engineering, and environmental science, where understanding motion over large distances is essential.
Current Use
Kilometer square second is primarily used in scientific fields that require the analysis of motion over large areas, particularly in astrophysics, geology, and environmental science. In astrophysics, for example, km²/s can be used to describe the acceleration of celestial bodies, where distances are vast and conventional units like meters become impractical. In geology, it assists in modeling the movement of tectonic plates or the flow of large lava fields over time. Countries that utilize the metric system, including France, Germany, and most of Europe, commonly employ kilometer square second in research and academic publications, as it aligns with the global standard for scientific communication. Additionally, in meteorology, it helps quantify wind accelerations over large geographical areas.
Fun Fact
The kilometer square second is rarely encountered in everyday life and is primarily used in scientific contexts.
Revolution Minute Secondrev/min/s
Target UnitThe revolution minute second (rev/min/s) is a unit of angular acceleration that describes how much the angular velocity of an object changes in one second, expressed in revolutions per minute. This unit is particularly useful in fields such as mechanical engineering and physics, where the rotational motion of objects is analyzed. One revolution corresponds to a complete rotation (360 degrees), and when this is calculated over a time period of one minute, it provides a measure of how quickly the object accelerates or decelerates its rotation. The unit is derived from the combination of revolutions (a measure of angular displacement) and time, allowing it to convey both the rate of rotation and the change in that rate over time.
Current Use
Revolution minute second is commonly used in various industries such as automotive engineering, aerospace, and robotics to quantify angular acceleration. In automotive engineering, it is essential for understanding how quickly a vehicle can change its rotational speed, which is crucial for performance analysis and safety features. Aerospace applications utilize this unit to evaluate the performance of aircraft engines and rotors, ensuring optimal operation during flight. In robotics, precise control of motors often requires measurements of angular acceleration to achieve desired motion profiles. Countries that actively use this unit include the United States, where imperial units are prevalent in various engineering fields, and European nations that apply the metric system in scientific research and industry.
Fun Fact
The concept of a revolution dates back to ancient astronomy, where it was used to describe the circular paths of celestial bodies.

acceleration • Non-SI
Definition
The kilometer square second (km²/s) is a derived unit of acceleration that describes how an object moves over a distance of one square kilometer in one second. This unit conveys the rate of change of velocity that an object experiences in a two-dimensional plane. It can be expressed as the distance traveled (in square kilometers) divided by the square of the time taken (in seconds). Acceleration is a vector quantity, indicating both magnitude and direction, and applies to various fields such as physics, engineering, and environmental science, where understanding motion over large distances is essential.
History & Origin
The concept of acceleration has roots tracing back to ancient civilizations, where philosophers like Aristotle and Archimedes began to explore motion. However, the formal definition of acceleration as a measurable quantity emerged during the Renaissance period with the work of Galileo and Newton. In the 17th century, Isaac Newton's laws of motion laid the groundwork for understanding acceleration quantitatively. The specific use of kilometer square second as a unit reflects the need for measuring acceleration over larger expanses of distance, particularly in fields like astrophysics and geology, where kilometers are more appropriate than meters.
Etymology: The term 'kilometer' is derived from the French 'kilomètre,' which combines 'kilo-' (meaning a thousand) and 'mètre' (meter). 'Square' refers to the area measurement, while 'second' stems from the Latin 'secundus,' meaning 'following' or 'second in order.'

Definition
The revolution minute second (rev/min/s) is a unit of angular acceleration that describes how much the angular velocity of an object changes in one second, expressed in revolutions per minute. This unit is particularly useful in fields such as mechanical engineering and physics, where the rotational motion of objects is analyzed. One revolution corresponds to a complete rotation (360 degrees), and when this is calculated over a time period of one minute, it provides a measure of how quickly the object accelerates or decelerates its rotation.

History & Origin
The concept of revolution as a measure of angular displacement dates back to ancient civilizations that observed celestial bodies, but the formalization of revolution as a precise unit occurred during the development of classical mechanics in the 17th century. The minute, as a subdivision of an hour, was established in the 14th century as a standard measure of time. The combination of these units into the revolution minute second for measuring angular acceleration reflects advancements in understanding rotational dynamics, particularly during the Industrial Revolution when machinery became more sophisticated.
Etymology: The term 'revolution' comes from the Latin 'revolutio', meaning 'a turn' or 'a rolling back'. 'Minute' derives from the Latin 'minuta', meaning 'small', and 'second' is from the Latin 'secundus', meaning 'following' or 'next'.
Current Use
Revolution minute second is commonly used in various industries such as automotive engineering, aerospace, and robotics to quantify angular acceleration. In automotive engineering, it is essential for understanding how quickly a vehicle can change its rotational speed, which is crucial for performance analysis and safety features.
