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 QC = 5,400 arcmin
1 arcmin = 0 QC
例子:
将15 四分之一圈转换为弧分钟：
15 QC = 81,000 arcmin
| 四分之一圈 | 弧分钟 |
|---|---|
| 0.01 QC | 54 arcmin |
| 0.1 QC | 540 arcmin |
| 1 QC | 5,400 arcmin |
| 2 QC | 10,800 arcmin |
| 3 QC | 16,200 arcmin |
| 5 QC | 27,000 arcmin |
| 10 QC | 54,000 arcmin |
| 20 QC | 108,000 arcmin |
| 30 QC | 162,000 arcmin |
| 40 QC | 216,000 arcmin |
