Wire Gauge Conversion Table
This table is the comparison chart for both AWG and other wire designations. Gages desginations are arranged in columns below. The abbreviations signify: AWG = American Wire Gauge, B&S = Brown & Sharpe SWG = Imperial Standard Wire Gauge - (British legal standard). The values are stated in closely calculated, approximate decimals of an inch, excluding the metric numbers. As a number of gauges are in use for various shapes and metals, it is advisable to state the thickness in thousands when specifying in gauge number. Metric wire gauge is 10 times the diameter in millimeters.
