U+33AE SQUARE RAD OVER S

U+33AE was added to Unicode in version 1.1 (1993). It belongs to the block CJK Compatibility in the Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is a Square composition of the glyphs r a d ∕ s. It has a Wide East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. In text U+33AE behaves as Ideographic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

The radian per second (symbol: rad·s−1 or rad/s) is the SI unit of rotational speed (angular velocity), commonly denoted by the Greek letter ω (omega). The radian per second is also the unit of angular frequency. The radian per second is defined as the change in the orientation of an object, in radians, every second.

Note that because the radian is a dimensionless unit, the radian per second is dimensionally equivalent to the hertz—both are defined as one s−1. This means that great care must be taken to avoid confusing angular frequency ω and frequency ν.

One of the important uses of the unit radian per second is in calculation of the power transmitted by a shaft. In the International System, widely used in physics and engineering, the power, p, delivered to the shaft is given by the product of ω (in radians per second) times the torque, τ, in newton-meters applied to the shaft. Thus, p = ω • τ, and the unit is the watt, with no numerical coefficient needed.

In other systems, the calculation is somewhat more complicated, because if one multiplies angular velocity in revolutions per minute (r.p.m.) times the torque in pound-feet, then a multiplicative constant is needed to give the result in horsepower.

An angular frequency, ω = 1 rad/s, corresponds to an ordinary frequency, ν = 1/2π Hz = 0.159 Hz approx. which in turn corresponds to a frequency of rotation = 60/2π rpm = 9.55 rpm approx.
