How do I calculate electrical wire size?
Here’s how you calculate AWG (American Wire Gauge) from the diameter of a wire:
- Find the ratio (R) of the wire diameter to either 0.005 inches or 0.127 mm.
- Use the equation n = -39 × log92(R) + 36 to find the AWG number.

How to calculate conduit size for wiring?
– Read down the first column on the fill table to find the wire gauge – Across from the wire gauge, you’ll find the maximum number of wires that can be placed inside your conduit diameter – Choose a number equal to or greater than the number of wires you’ll put inside the conduit
How do you calculate conduit size?
– Calculating Wall Thickness. – σ s =PN. (da-s/20.s)=PN.S. – Calculating Standard Dimension Ratio. – SDR = da/s. – Calculating CLR (Center Line Radius) for Bend Angle. – 3.1416 (2×2.2) = 13.823/360 = 0.0384. – 0.0384 x 35 = 1.344”
