What is the difference between awg and swg

The thinnest wire diameter of an SWG wire is 0. The usage of the SWG system has declined over the years. Currently, it is mainly used to measure guitar wires. However, industries that use wires for non- electrical purposes also use the SWG system. The standard wire measuring system used in America is AWG.

The abbreviation stands for the American Wiring Gauge. Wires measured using this system tend to be smaller than the ones measured by the SWG system. With 40 steps, AWG offers better current conduction and protection. With the use of SWG gradually fading away, it is widely used in the measurement of electric wires.

The smallest diameter of an AWG wire is 0. This standard is defined by the diameter of the electrical wire that is being measured. Therefore, it is the physical size is what matters most. Also, the larger the physical size of the wire the smaller the wire gauge according to the AWG measurements.

SWG was the legal standard for measuring wire in the United Kingdom as of All of the SWG measurements are in metric sizes. In most cases of use of the SWG measuring standard the sizes will be rounded up which does affect the accuracy. Most noteworthy, both standards are based on the physical size of the wire being measured. Also, both share common wire numbers that express those physical sizes. Finally, metal measuring plates are used to determine the size of the wire.

The most obvious difference is the standard of measurements. AWG is recorded in what is referred to as the imperial system of measurement. This system of measurements is in inches. Therefore, the American standard is different from the SWG system which uses the metric system of measuring. SWG has 50 steps, resulting in a thinnest wire diameter of 0.

AWG only has 40 steps and the smallest wire diameter under it is 0. The size of the wire is quite important not only because it adds to the strength of the wire, but because it directly correlates to the amount of current it can carry.

If you use a wire that is too small for the current that needs to pass, the wire would eventually heat up and lead to fires. Despite that, SWG is still used in other industries that do not actually deal with electrical wires. An example of this would be guitar wires, which still use the SWG size standards. Cite APA 7 , l.
