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 oct = 2,700 arcmin
1 arcmin = 0 oct
例子:
将15 八分之一转换为弧分钟：
15 oct = 40,500 arcmin
| 八分之一 | 弧分钟 |
|---|---|
| 0.01 oct | 27 arcmin |
| 0.1 oct | 270 arcmin |
| 1 oct | 2,700 arcmin |
| 2 oct | 5,400 arcmin |
| 3 oct | 8,100 arcmin |
| 5 oct | 13,500 arcmin |
| 10 oct | 27,000 arcmin |
| 20 oct | 54,000 arcmin |
| 30 oct | 81,000 arcmin |
| 40 oct | 108,000 arcmin |
| 50 oct | 135,000 arcmin |
| 60 oct | 162,000 arcmin |
| 70 oct | 189,000 arcmin |
| 80 oct | 216,000 arcmin |
| 90 oct | 243,000 arcmin |
