Why are needle gauges backwards?
Beyond international standards, another source of confusion is why wire gauge sizes appear to be backwards of what they should be—as the physical width of the gauge increases the numerical value assigned to it decreases. The drawing and stretching decreases the physical size of the wire making it longer and thinner.
