In Reply to: How many strands of 30 AWG twisted to make 20AWG? posted by lukpayat on August 1, 2000 at 07:09:55:
You would need about 10 strands. The math is simply dividing the 20 gauge cross section area by the 30 gauge area. The wire gauge diameters are available in a chart or website like http://www.coilcraft.com/awg.html. The area is simply pi * radius * radius (where pi = 3.1414).A simple approximation is that every doubling of the number of conductors will lower the gauge about three numbers, two 30 AWG wire will equal one 27 AWG, four = 24AWG, eight = 21AWG.
