AWG to MM2

The electrical engineer makes a lot of calculations. Sometimes when an engineer visits a different country and his calculation may differ to a new country. Thus, here is a list of cross-reference AWG (American Wire Gauge) to mm2 (Square Millimeter).

Cross-reference AWG to MM2 chart.

    I am about to rewind a auto AC magnetic coil. Is it correct to use enamel coated wire of 26AWG/0.15mm. However I am not sure of the length of the wire required for the winding. Can you help me on this. TQ.

      First verify the size used originally, if you’re not sure the original wire was 26 AWG, try to measure a small section of the original winding wire with a micrometer. Using too thin a wire can overheat or under perform. Using too thick can reduce the number of turns, weakening the coil. Use this formula to calculate the distance:

      Length = N × Average Turn Length

      Where:

      N = number of turns.

      Average Turn Length ≈ Mean length of one loop (based on coil dimensions).

      Always buy at least 10–20% extra wire to account for tension, overlap, or error.

      Make sure to replicate the same direction and tight winding.

      After winding, check resistance of the coil with a multi-meter and compare it to the old one (if available).
