Metric pipe size question

[Icy]

my old man went out and got me some pipe today. But im unsure if its anygood he said it was ok but i dont trust his maths lol. :D he said its 1/4 but i dont belive him rofl.

anyway info as follows:
Copper Tube Microbore Coil
10mm OD x 07mm ID x 10m

he also said they had some
8mm OD x 06mm ID x 10m

so yeah if anyone can help with this it would make me very happy :banana:

[the_new_guy]

7mm is about .27''
6mm is about .23''

10mm ~ 3/8" (9.525mm)
6mm ~ 1/4" (6.35mm)

k so... basicaly my 7mm ID 10mm OD is wrong then so i got to take it back. DOH!

6mm ID = 1/4"
7mm ID = 9/32"
8mm ID = 5/16"
10mm ID = 3/8"
12mm ID = 7/16"

dont suppose anyone has a list of all common sizes used in phase change in metric and imperial?

also is it the ID or OD im ment to be using for phase change like this? http://www.coolfreeze.com/mail-order/itmidx12.htm

Thanks for all your help!
