In addition to Rogan's notes;
Dividing any dur by another dur will give you a float so;
second / ms => float thousand;
This is, BTW, a 100% proper; in physics, if I divide a meter into bits that
are a centimetre long then the result will be a 100, a amount without a
unit. If I'd divede the same meter into a hundred(without unit) bits the
result will be a centimetre (or 0.01 metre) so definitely with a unit.
Duration inherently expresses time and so it will have a unit, unlike

You may also be interested in .period( dur ), a member function of many
oscillators that sets the period of the wave shape and which is just a
alternative way of expressing the frequency. This can be quite useful for
setting LFO speeds relative to a piece's BPM.
Hope that helps,
