Yes, Sheldon he has separate American and British English versions of pages!!!
For example, Kross bicycle (2017) had a Schwalbe tyre with markings:When inflated, the tires were about 3.5cm wide as measured with a ruler.
42-622 (28 x 1.60, 700x40C)
And the Mavic A319 rim had markings:
622x19C
In this:
- ISO (Etrto): 42-622. So:

- 622 is the bead seat diameter. The actual inflated tire is going to be even wider.
- imperial: 28 x 1.60
- French: 700x40C:
