How big is 5mm?
Besides "about this big".
On a project unrelated to my 944 (platform bed), the instructions for a piece of hardware I bought (shelf pin) says drill a 5mm hole. What is the equivalent?
I know I can compare the drills to the piece like I usually do. I'm trying to practice the mantra of measure twice cut once.
Surely with all the tire conversion chart links, option code links, someone has a metric conversion.
TIA

Something screwy is going on here! I'm clicking on Tom R's "how big is 5mm?" thread, but keep landing here. About 3/16" Tom, 28mm to the inch.
EDIT; Even screwier, the reply ended up in the right place, instead of the "ABS (or was it airbag) light reset" thread. Now I'm really

Umm, its actually 25.4 mm to the inch (exactly).
So 5 mm / 25.4 = .1968 which is a little bigger than 3/16ths, as mentioned...

Damn Americans...get with the program!! 
Metric is really easy...really!! 5mm is half of 10mm...which is 1 cm...so, 5mm is 0.5cm. Now, there's 2.54 cm in 1 inch, so 1cm would then be equivalent to 0.3937 in...so, 0.5cm would obviously be 0.1969 inches. Jeesh, see how easy that was? So that's just over 3/16". Yah, like Dave said.

5mm is 5mm, that is the size of it. Stop trying to convert - think metric, the people who designed and built your car did. If you keep wasting time thinking of foot & inch equivalents you will never get a feel for the system.

Yeah, get with the program. Even the inventors of the 'Imperial Standard' are using... guess what.. METRIC !!! Dave, I think you're getting your grams conversion mixed up with your millimeters.

Will Big Red calipers fit inside 406.4-mm wheels, or do I have to go to the 431.8's?
Maybe if the offset is about 2 inches?
Anybody remember the Michelin TRX wheels & tires on Mustangs and Ferraris? I think the wheel diameter was in mm (390, IIRC).

Yeah, but it has a better ring to it than "I'll have two 568 millilitre servings of lager and 30 grammes of deep fried crunchy potato snacks"
And before anyone gets funny about the numbers, remember that our pints are 20 oz.

Having spent the late seventies / early eighties in California, I remember the attempts to introduce metric to schoolchildren (including me). It was always, 30 cm is about 1 foot, 1 km is just over 6/10ths of a mile etc. etc. I could never grasp it. If someone said "that's 6 metres" I would frantically try and convert to feet. When I started to just accept the unit for what it is, I began to get somewhere. If someone says 19 feet 4 inches, I think in those units, the distance I see in my head is about the same.
The analogy I can think of is that of foreign currency. If I have to buy something when in another country, the natural tendency is to compare prices of things with those in my home country, but what I should be doing is comparing local prices, putting my own currency out of my head - it doesn't matter what I could get it for at home, I'm not there. In other words, "When in Rome..."
