I doubt you'll find a suitable metric substitute for just the original leg leveler.
- If you can't find an SAE/imperial-measurement leveler, you're better off replacing both the leveler and the plate it threads into.
I can get the length in cm, but how on earth do I get cm from 1/2"x13? I have no idea what the x13 means
When describing threads, you need to know the diameter and the pitch -- the distance between threads.
1/2" = 12.7mm (diameter)
The
x13 indicates 13 threads per inch ==> 1"/13 threads = 25.4mm/13 threads = 1.9538mm/thread (pitch)
- Imperial pitch can also be indicated with a dash. i.e. a #4
-40 machine screw indicates 40 threads per inch.
