速度是对象移动的速度，而速度是指定方向的速度。它以每秒米（m/s）为单位进行测量。
1 ly/yr = 1 m/s
1 m/s = 1 ly/yr
例子:
将15 每年光年转换为仪表每秒：
15 ly/yr = 15 m/s
| 每年光年 | 仪表每秒 |
|---|---|
| 0.01 ly/yr | 0.01 m/s |
| 0.1 ly/yr | 0.1 m/s |
| 1 ly/yr | 1 m/s |
| 2 ly/yr | 2 m/s |
| 3 ly/yr | 3 m/s |
| 5 ly/yr | 5 m/s |
| 10 ly/yr | 10 m/s |
| 20 ly/yr | 20 m/s |
| 30 ly/yr | 30 m/s |
| 40 ly/yr | 40 m/s |
| 50 ly/yr | 50 m/s |
| 60 ly/yr | 60 m/s |
| 70 ly/yr | 70 m/s |
| 80 ly/yr | 80 m/s |
| 90 ly/yr | 90 m/s |
| 100 ly/yr | 100 m/s |
| 250 ly/yr | 250 m/s |
| 500 ly/yr | 500 m/s |
| 750 ly/yr | 750 m/s |
| 1000 ly/yr | 1,000 m/s |
| 10000 ly/yr | 10,000 m/s |
| 100000 ly/yr | 100,000 m/s |
