I have also had help from various surfers that have pointed out errors, for which I am eternally grateful Why is the diameter value greater than the area value? The cable diameter in millimeters is not the cable cross-section in square millimeters. There have been many times in my life when I have been confused by references in literature to wire gauges that may be common in some places, but are not universal. And there is always the nice but unsatisfactory advice to use for security reasons a thicker and hence more expensive cable. Calculator: Ohm's law. The "unit" is usually millimeters but it can also be inches, feet, yards, meters metresor centimeters, when you take for the area the square of that measure. Using the gauge plate

British Standard Wire Gauge is a set of wire sizes given by BS (now withdrawn), and is generally abbreviated to SWG. It is also known as: Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but is still used as a Cross sectional area in square millimetres is now the more usual size. The thickness of a wire is often given as a Standard Wire Gauge, or SWG. Standard Wire Gauge, Diameter, Turns of wire, Cross-sectional area, Res.
