There's a piece I'm practicing that's in 6/8 and has written on it that a dotted crotchet is equal to 66.
I want to practice this with a metronome set to a 6/8 time signature because I want to be able to practice a hard semiquaver section while also being able to keep track of where I am in the bar.
What should I set my tempo to so that I can do that and how can I find that out in the future if I need to do it again?
P.S. Sorry if I missed any obvious solution or something, I'm really tired.
If a dotted crotchet (corresponding to 3/8) is 66 (this means in 1 minute there 66x3/8 -> you have to multiply the 66x3x1/8 = 198. This is what you have to choose if you want to count the time based on 1/8. But it will be better you start with a slower tempo, maybe 1/8=150.

As you can see in this example you always have
to know how many notes of the unit (?/8) in the given time signature (6/8) are contained in the given tempo unit (dotted quarter=3/8)
than you must multiply the counter (3) of the ratio (/8) with the tempo (66) and you have the b.p.m. for your metronome.
A dotted crotchet is half a bar in 6/8. So there will be two clicks per bar to follow. Each click will represent three quavers. Or six semis. If you triple the metronome speed to 198, each click will represent two semis.
Obviously, in practising, you'll slow that a bit - maybe 160, to tidy up the whole timing.
