A little geometry/trigonometry goes a long way...

30 degree crosswind... multiply by 0.5 to get the crosswind component

[snip]

The method I've been taught is to use the clock face.

15 degrees off if quarter past, so use a quarter. 30 degrees is half
past, use half. 45 degrees is 45 minutes past, so use 3/4. 60 degrees
or above use the full wind speed.


Mmm, never heard i that way before,

Good,.
