AWG to MM converting

Hi,

Currently building a full harness for my Nissan 200SX, in the UK, and am piecing together all materials required.

I understand 22gauge is converted to 0.64mm or 0.33mm2, however from UK suppliers, would you recommend 0.50mm cable or go bigger to 0.75mm for safety?

Also, nigh on impossible to find shielded twin at 0.75mm, so im assuming 0.50mm would be acceptable considering its only a signal?

Many thanks,

24 AWG (.51mm dia) is certainly adequate for a signal wire.

For conversion, you might use a chart like this one:
