Unit Explanations

Radian Secondrad·s

Source Unit

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.

ω = θ/t

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 Hour°h

Target Unit

A degree hour (°h) quantifies the energy required to change the temperature of a substance by one degree Celsius over the span of one hour. It is often used in the context of heating, ventilation, and air conditioning (HVAC) systems to estimate energy consumption and efficiency. The degree hour is an essential metric in building energy management, allowing for the assessment of thermal loads and energy performance. For example, if a building requires 10 degree hours to maintain a comfortable temperature, this indicates that for each hour, the temperature differential to achieve comfort is one degree, necessitating energy input to achieve this effect.

°h = (Temperature Difference in °C) × (Time in hours)

Current Use

Today, degree hours are widely used in the HVAC industry to evaluate system performance and energy consumption. Engineers and energy managers rely on degree hours to optimize heating and cooling strategies in residential and commercial buildings, ensuring comfort while minimizing energy use. The metric is also used in agricultural practices to assess crop growth conditions.

Fun Fact

The degree hour can be used to calculate energy savings from implementing energy-efficient HVAC systems.

rad·s

Radian Second

velocityNon-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.
