Re: HOW TO CONVERT SQ MM OF A CABLE TO DIAMETER, EG. CABLE SIZE IS 185SQ.MM WHAT IS THE DIA OF THE CABLE??????????????
# 1
your power cable size is 185 sq mm

now diameter of the cable is

d= square root of area of the cable* 4*7/22

d=square root of 235.45

# 2
x=pie*r2
wherex=185
185=3.142*r2
r2=185/3.142
r2=58.9
r=7.7
then dia=15.4

Cable size represents one core area. First convert the area
into dia(a). The cable diameter is calculated by adding
sleeve, armour, outer sheeth dia to 3*a +1/2*a for 3 1/2
core cable. Exact size can be seen in cable manufacturers
catalogue.
