+
+    Plane and solid angles, when expressed in radians and steradians respectively, are in effect
+    also treated within the SI as quantities with the unit one (see section 5.4.8). The symbols rad
+    and sr are written explicitly where appropriate, in order to emphasize that, for radians or
+    steradians, the quantity being considered is, or involves the plane angle or solid angle
+    respectively. For steradians it emphasizes the distinction between units of flux and intensity
+    in radiometry and photometry for example. However, it is a long-established practice in
+    mathematics and across all areas of science to make use of rad = 1 and sr = 1.

 Angular Frequency
-=================
+-----------------
 
 `Hertz` is a unit for frequency, that is often also used for angular frequency. For example, a shaft spinning at `60 revolutions per minute` will often be said to spin at `1 Hz`, rather than `1 revolution per second`.
 
-By default, pint treats angle quantities as `dimensionless`, so allows conversions between frequencies and angular frequencies. The base unit for angle is the `radian`. This leads to some unintuitive behaviour, as pint will convert angular frequencies into frequencies by converting angles into `radians`, rather than `revolutions`. This leads to converted values `2 * pi` larger than expected:
