角度是两个相交线或表面之间旋转的度量。它以程度（°）或弧度（rad）为单位进行测量。
1 TC = 7,200 arcmin
1 arcmin = 0 TC
例子:
将15 第三圈转换为弧分钟：
15 TC = 108,000 arcmin
| 第三圈 | 弧分钟 |
|---|---|
| 0.01 TC | 72 arcmin |
| 0.1 TC | 720 arcmin |
| 1 TC | 7,200 arcmin |
| 2 TC | 14,400 arcmin |
| 3 TC | 21,600 arcmin |
| 5 TC | 36,000 arcmin |
| 10 TC | 72,000 arcmin |
| 20 TC | 144,000 arcmin |
| 30 TC | 216,000 arcmin |
| 40 TC | 288,000 arcmin |
| 50 TC | 360,000 arcmin |
| 60 TC | 432,000 arcmin |
| 70 TC | 504,000 arcmin |
| 80 TC | 576,000 arcmin |
| 90 TC | 648,000 arcmin |
| 100 TC | 720,000 arcmin |
