Tape winding length calculation formula

Tape winding length calculation formula

First measure the thickness of the tape, and use H to represent the thickness of the paper tube of the tested tape; the measured value here is: 9 mm.

Then measure the length of the tape from the inner circle to any side, and use the letter N to represent the measured length; the measured value here is: 89 mm.

Then use a ruler to measure the thickness of the paper tube of the tape, and use T to represent the thickness of a single layer of tape; the measured value here is 0.05 mm

The formula to calculate the tape length is --H/T*N*3.14. Take the above example: 9/0.05*89*3. 14/1000=50.3028 meters. Therefore, this reel of tape can have 50.328 meters.

胶带缠绕长度计算公式

先测量胶带厚的厚度,用H来代表所测试的胶带的纸管厚度;这里的测出的值为:9毫米。

再测量胶带从内圆到任意一边的边的长度,用字母N代表所测的长度;这里的测出的值为:89毫米。

再用尺子测量一下胶带的纸管厚度,用T代表胶带的单层厚度;这里的测出的值为0.05毫米

计算胶带长度的公式为--H/T*N*3.14。以上面为例: 9/0.05*89*3. 14/1000=50.3028米。因此,这一盘胶带能有50.328米。
