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.
Degree Minutedm
Target UnitA degree minute, abbreviated as 'dm', is a unit of angular measurement that represents one-sixtieth of a degree. This unit is often used in navigation and geographic coordinate systems, where angles are measured in degrees, minutes, and seconds. Specifically, one degree is divided into 60 minutes, and each minute can be further divided into 60 seconds, creating a hierarchical system for precise angular measurement. The degree minute facilitates the expression of small angles in a more manageable format, particularly in fields requiring high precision such as astronomy, cartography, and geodesy.
Current Use
Degree minutes are primarily used in navigation, cartography, and astronomy. They provide a practical way to express angular measurements needed for positioning and mapping. In navigation, degree minutes are crucial for determining latitude and longitude on maps, while in astronomy, they are used for locating celestial objects. The precise nature of degree minutes allows for effective communication of angles, especially in coordinates, enhancing accuracy in scientific and practical applications.
Fun Fact
The concept of dividing degrees into minutes and seconds allows for representing angles with extraordinary precision, crucial in navigation.

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.

Degree Minute
velocity • Non-SI
Definition
A degree minute, abbreviated as 'dm', is a unit of angular measurement that represents one-sixtieth of a degree. This unit is often used in navigation and geographic coordinate systems, where angles are measured in degrees, minutes, and seconds. Specifically, one degree is divided into 60 minutes, and each minute can be further divided into 60 seconds, creating a hierarchical system for precise angular measurement. The degree minute facilitates the expression of small angles in a more manageable format, particularly in fields requiring high precision such as astronomy, cartography, and geodesy.
History & Origin
The use of degrees has ancient origins, dating back to the Babylonians who divided the circle into 360 degrees based on their base-60 numeral system. The division into minutes and seconds emerged later, formalized during the Renaissance when more precise measurements in navigation became necessary. The degree minute was adopted in various scientific fields to improve accuracy in angular measurements, particularly in navigation and astronomy, as it allowed for a finer resolution of angles compared to degrees alone.
Etymology: The term 'degree' is derived from the Latin 'gradus', meaning 'step', while 'minute' comes from the Latin 'minuta', meaning 'small' or 'small part'. Thus, 'degree minute' essentially translates to 'small step of a degree'.
Current Use
Degree minutes are primarily used in navigation, cartography, and astronomy. They provide a practical way to express angular measurements needed for positioning and mapping. In navigation, degree minutes are crucial for determining latitude and longitude on maps, while in astronomy, they are used for locating celestial objects.
