Normally if you buy a whole set (rather than individual bits) you will get something like that with it.

I bet there aren't many yuppies who keep info on tap drill sizes in their phones! :)

Metric is very easy. you minus the pitch from the diameter to give the drill size

M16x2.0 pitch = 14mm drill bit

it also has something to do with material hardness as well but probably not worth going into unless the thread strength is critical

What's this 'metric' gobbledygook you speak of?
