Question:
wire diameter, usually how we usually call it rough, such as: 1.76cm, also call it how much cross-section, two different name for , how to mutual conversion?

Answer:
wire cross-sectional area = unit of mm2
wire cross-sectional area = 3.14 * pi diameter

Answer:
I am an electrician, the general what we call wires, such as: 1.5 or 2.5, refer to wire cross-sectional area, in units of square millimeters, that is 1.5 mm or 2.5 mm square, the market also comes with a standard cross-sectional area of wire, generally 100 meters 1.

电线直径的换算方法

分类:家居装饰

问题:
电线的直径,平时我们通常叫它有多粗,如:1.76cm,也有叫它截面有多大的,两种不同的叫法,如何进行相互的换算?

回答:
电线截面积=单位平方毫米
电线截面积*圆周率3.14=直径

回答:
我就是一名电工，一般我们叫电线多大，如：1.5或2.5，都是指电线的截面积，单位是平方毫米，即1.5平方毫米或2.5平方毫米，市场上销售时也是以截面积为电线的标准，一般一百米一盘。如你要换算成直径，直接用截面积除以圆周率3.14，然后开平方即可。2005-12-09
