Welcome mate.
Nice one Maxfield!!! Can you imagine drving down the road at 70kmph and trying to think........'right ok 70 x 3 divide 5.....eerrrrr, eeeerrrrr......ooops speed camera'
All I do is 50kmph for 30, 100kmph for 60. Theyre not exact but if you keep just under you wont get a ticket.

cant you just get a standard set of clocks and swap the red needle over to the mph unit and install it into the cluster.
Ive got M3 clocks in mine but i cant remember if i did that or i just swapped the black backing with the numbers on it for the kph one.I think i did the first one.
heres mine:

Off the top of my head
16,32,48,64,80,96,112 kms
10-70mph
You'll soon learn. Alternatively print out my post and stick it to the instrumenter cluster screen.

I just remember 50,65, and 100 (30,40 and 60)
oh and stricly speaking, km*3 and divide by 5 is wrong
it should be km*5 and divide by 8. (as shown in Rich_w's post),
btw when checking on satnav a few weeks ago, mine was overreading slighlty ~ at least 5%(no surprise).
