What is .7 mm in thou.

0.0275591" IOW near enough 27.6 thou. Mike.

Thanks Mike. My BMW cd gives measurements in mm instead of thou and I was stuck. Cheers pete

Just for future reference (not having a dig), if you type a sum into Google it'll usually work it out for you. Try 0.7mm in inches.

Before the 'net came into being I always multiplied the figure in 'mm' by 4. IMO close enough. 7mm x 4 = 28 thou'.

But if you are near it wen you need a conversion this place is pretty good ..

All the best ..

Buy some metric feeler gauges, they are cheap enough and yes you can actually buy them.

eeh! 0.7mm is 0.7mm, you shouldn't need to convert to inches.

You'll be stuck with much else DIY on a BMW if you don't equip yourself with basic metric tools.

Since I find imperial measurements totally confusing I usually have the reverse problem of converting *to* metric ;)

This is a useful conversion program:

As long as you can remember '25.4' I'd suggest it's easier, and more convenient to use a calculator. Multiplying any figure in inches, or decimals of an inch, by 25.4. gives the answer in mm's. And deviding mm's by 25.4 converts mm's to inches. Mike.

Correction.

You do if you have an old (proper) set of feeler gauges.

I prefer to work in metric, for most stuff it's 1/100ths of a mm. While in Imperial there's a thousand of the little bleeders.

Fair enough, and of course it's only what the software does, but the advantage is that it knows a few more values for other conversions too :)

The reason I asked was because another poster had told me to open my gaps up to 40 thou. I checked what the big book of words said and came up with .7mm and now I know that is 27 thou I am not about to follow the other chaps advice;-) pete

Look here very young person. I am still having trouble telling the difference between half a crown and 12.5 p. ;-) A penny for your thoughts, errrr now is that 1p or 2.4 old pennies and please do not ask me what an old penny is or I will start going on about farthings and how we used to be able to go out and leave the door unlocked and all that old bollocks;-) pete

I have metric tools but not a metric brain;-) I blame it all on the EU myself or Thatcher. pete

Bugger, you've twigged me;-) alright I'll ask my g/children;-) pete

40 though is 1mm near enough. Fester plugs are (according to a conversation in a garage I overheard) 1mm gap but that is a bit big normally.

Depends on what sort of ignition you have I suppose.
