Unit Explanations
Radian Secondrad·s
Source UnitThe radian second (rad·s) is a unit of angular velocity that quantifies the rate of rotation in terms of the angle rotated in radians per unit time, specifically seconds. One radian corresponds to the angle subtended at the center of a circle by an arc length equal to the radius of that circle. Thus, when measuring angular displacement, the radian second indicates how much of a full rotation (2π radians) occurs in one second. In mathematical terms, if θ is the angle in radians and t is the time in seconds, then angular velocity ω is represented as ω = θ/t, where ω is in rad·s.
Current Use
The radian second is widely used in various fields such as physics, engineering, and robotics to describe the rotational motion of objects. It is essential in analyzing systems involving gears, motors, and celestial mechanics. The unit is integral in the design of control systems, where the control of angular velocity is crucial for performance. In addition, it is commonly used in simulations and modeling of dynamic systems in both academic and industrial settings.
Fun Fact
The concept of a radian is inherently tied to the geometry of a circle, making it a natural fit for circular motion analysis.
Revolution Hourrh
Target UnitThe revolution hour (rh) is a non-standard unit of measurement used to quantify the distance traversed by an object undergoing circular motion at a constant speed for one hour. It is defined as the total number of complete revolutions (or cycles) an object makes in one hour, multiplied by the circumference of the circular path traveled. This unit is particularly useful in contexts involving rotational dynamics, such as in mechanical engineering and robotics. The formula for calculating revolution hours can be expressed as: rh = (N × C) / 3600, where N is the number of revolutions and C is the circumference of the circular path.
Current Use
Today, the revolution hour finds application in various industries where rotational speed is crucial. It is notably used in mechanical engineering, automotive design, and robotics to assess the performance of engines, turbines, and other rotating machinery. By providing a standardized way to measure how far an object travels in circular motion over time, it aids in diagnostics and efficiency assessments, making it a vital component in the design and testing of rotational systems.
Fun Fact
A revolution hour can be converted to linear speed, allowing for direct comparisons with other speed metrics.

velocity • Non-SI
Definition
The radian second (rad·s) is a unit of angular velocity that quantifies the rate of rotation in terms of the angle rotated in radians per unit time, specifically seconds. One radian corresponds to the angle subtended at the center of a circle by an arc length equal to the radius of that circle. Thus, when measuring angular displacement, the radian second indicates how much of a full rotation (2π radians) occurs in one second. In mathematical terms, if θ is the angle in radians and t is the time in seconds, then angular velocity ω is represented as ω = θ/t, where ω is in rad·s.
History & Origin
The concept of angular measurement has existed since ancient times, but the radian was formally defined in the 18th century by mathematicians such as Leonhard Euler. The radian as a unit became widely accepted for describing angular measurements due to its mathematical convenience, notably in calculus and trigonometry. The use of radian seconds emerged as a natural extension in physics and engineering to quantify angular velocities, particularly in rotational dynamics and wave mechanics.
Etymology: The term 'radian' is derived from the Latin word 'radius,' meaning 'ray' or 'spoke,' reflecting the relationship between the radius of a circle and the arc length it subtends.
Current Use
The radian second is widely used in various fields such as physics, engineering, and robotics to describe the rotational motion of objects. It is essential in analyzing systems involving gears, motors, and celestial mechanics. The unit is integral in the design of control systems, where the control of angular velocity is crucial for performance.

History & Origin
The concept of measuring rotational motion dates back to ancient civilizations where simple devices like wheels were used. However, the specific term 'revolution hour' has evolved from the need to quantify rotational speed in modern mechanical contexts. Its formal recognition in the scientific community emerged in the 20th century, particularly with advancements in engineering and kinematics, emphasizing the importance of speed measurement in rotating systems.
Etymology: The term 'revolution' originates from the Latin word 'revolutio', meaning 'to turn over' or 'roll back'. Coupled with 'hour', derived from the Old French 'ure', meaning 'time', it describes the time taken for a complete turn in a circular motion.
