Wire Gauge to MM conversion Guide

As a rough guide here are the conversions from wire gauge to mm:

Gauge                 MM

34                       0.16

32                       0.20

30                       0.25    

28                       0.32

26                       0.40

24                       0.51

22                       0.64

20                       0.81

18                       1.02

16                       1.29

14                       1.62

12                        2.05


It is OK to round it  , i.e. 20 gauge would be 0.8 mm

That's very useful - give us an idea of what sizes we'll need.
