Wire Calculators In commerce, the sizes of wire are estimated by a device, also called gauges, which consist of plates of circular or oblong form having notches of different widths around their edges to receive wire and sheet metals of different thicknesses. Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to be of, say, No. 10, 11, 12, etc., of the wire gauge. The circular forms of wire gauge measurement devices are the most popular, and are generally 3¾ in. (95 mm) in diameter, with thirty-six notches; many have the decimal equivalents of the sizes stamped on the back. Oblong plates are similarly notched. Rolling mill gauges are also oblong in form. Many gauges are made with a wedge-like slot into which the wire is thrust; one edge being graduated, the point at which the movement of the wire is arrested gives its size. The graduations are those of standard wire, or in thousandths of an inch. In some cases both edges are graduated differently in order to allow comparison between two systems of measurement. A few gauges are made with holes into which the wire has to be thrust. All gauges are hardened and ground to dimensions. In some applications wire sizes are specified as the cross sectional area of the wire, usually in mm². Advantages of this system include the ability to readily calculate the physical dimensions or weight of wire, ability to take account of non-circular wire, and ease of calculation of electrical properties.

Don’t download. Pop up without end. ### 2/5 — Needs add-free version *2020-06-20* The app is great, except for the adds. I try to use this when I’m trying to get something accomplished, but I end up having to wait for ridiculous adds to end. I would gladly pay for an add free app. ### 1/5 — Can't get anything done with all the ads *2017-12-17* It seems like every time you tap on a button another add pops up in your face. Our use this app for five minutes then removed from my phone. ## Frequently asked questions about Wire Calculator ### What is Wire Calculator used for?
