642mm

I just picked up a Nokia tube and noticed that it says it
is good for tyres of "25-32" & "609-642". Okay, I know
609mm is 27x1½, but what is 642mm?

My God, it's a cell phone, man!

I don't know what either 609 or 642 are. 622mm is 700C and 630mm is 27". You can use the tube for either of those.

Even Sheldon's "Tire Sizing" page, sheldonbrown.comtireOpen ↗
sizing.html has no listing for either 609 or 642.

630mm is 27". You can use the tube for either of those.

What?

700C are 622. 27" are 630 Roadsters are 642. 609 is roughly
the ancient USA size 26 x 1.375.

The tube manufacturer is showing more optimism that I would.
